Is Your Mac Ready for macOS Catalina?

go64-mac-icon-100801664-large(See my other Tech Tips posts) – Every time a new version of macOS is released we have to consider “Is my Mac ready for the update?”.

Before you begin your upgrade make sure you have a full backup. Run Timemachine to capture any recent changes in your system. If you have the extra disk (and you really should do this), make a clone of your boot drive with an App like Carbon Copy Cloner. These steps will make it far easier to revert back to your current version of macOS if you run into problems after upgrading to Catalina.

This would also be a good time to ‘Tune-Up‘ up your Mac before you perform the upgrade. In particular, remove unneeded Apps and files.

This year there are two factors to consider. The first is whether or not your Mac hardware is capable of running Catalina. Generally speaking the 2012 or newer Macs are compatible. To find out for sure if your Mac can be upgraded refer to “macOS Catalina is compatible with these computers” from Apple.

The second thing to check is if all of your Apps are 64-bit. With Catalina the older 32-bit Apps will no longer run.

You can check your Apps two ways.

  1. The first way is to check in About My Mac. I wrote about how to do this in April of 2018 in “ARE YOUR MAC APPS ALL 64-BIT?“. I will let you check out that article for the details, but the essence is to go to “Overview:System Report:Software: Applications”. A column there indicates whether each App is or is not 64-bit compatible.
  2. A somewhat easier way to check your system is by using the Go64 App. This App is free (though donations are accepted) and can be downloaded from the vendor’s website. This App is recommended by:
    1. Macworld
    2. MacSparky (David Sparks of Mac Power Users podcast
    3. The Mac Observer
    4. Christian Boyce (Christian will be the featured speaker at the October 8th CapMac meeting in Austin)

Screen Shot 2019-10-05 at 3.28.35 PM.pngIf you download the App, then run it. You will get a report (see example above) of all Apps you currently have installed that are not 64-bit. Clicking on those software packages will provide further information. Links are also supplied for the vendors to facilitate getting the latest version of the software. As you can see I still have several 32-bit Apps on my Mac.

Once you have a list of your non-64-bit Apps you have a few choices:

  1. upgrade all the Apps you regularly use to a 64-bit version
  2. find 64-bit Apps that will replace your current 32-bit Apps
  3. delay migrating to Catalina until you do 1 or 2 above

A Look Back at ‘John’s Notes’ for June 2019

I have been seeing other Bloggers post a monthly review of what they have posted. I thought that I would give that a try. This is my first monthly summary and I will see how you, my readers react to it. You may see some posts listed more than once when they fit into multiple categories. 

If you have an opinion one way or the other about my monthly summary, please give me your feedback.

What I’ve read and reviewed:

Believe it or not, publishing book reviews was how I started Blogging. My first review appeared in Spring 2014. Since then I have been able to complete more than 100 books each year and write a review of each. 

  1. Book Review: “Fighting the People’s War: The British and Commonwealth Armies and the Second World War”
  2. Book Review: “The Atlantis Deception”
  3. Book Review: “Conspiracy of Lies”
  4. Book Review: “The Oppressed”
  5. Book Review: “The Darkest Year: The American Home Front 1941-1942”
  6. Book Review: “Darkness” 

The Mac and iOS

Mac Tech Tip – Skip the Save Prompt

Screen Shot 2019-05-25 at 2.13.03 PM

(See my other Tech Tips) – Are you annoyed by the dialog box asking if you want to save a document when closing a Mac App? I was, so I found out how to eliminate that.

Screen Shot 2019-05-25 at 2.15.28 PM

Just open the System Preferences and select “General”. Towards the bottom of the panel, there is a checkbox for “Ask to keep changes when closing documents”. If you uncheck that box, then anytime you close an App any open documents will be automatically saved including any changes you might have made.

This isn’t a big thing, but it improves my productivity as I no longer have to deal with the save prompt.

Which Format Should You Choose For An External Drive?

Tech Tips– Most of us use some sort of external USB attached storage on a regular basis. It is important to keep in mind that media can be formatted in many different ways. Which filesystem you format an external drive with depends on the system(s) you plan to use it with. That said, there are many different filesystems to choose from


For Linux systems, the most common format is ext3 or ext4. But neither of those formats of disks can be natively read by your Mac. You can, with the use of the third party software such as “FUSE for Mac” or “extFS for Mac by Paragon Software“, read ext3 or ext4 disks. 


Our current Macs use disks with either the “Mac OS Extended” (HFS+) or the more modern “Apple File System” (APFS) filesystem.

You may be able to mount and read an HFS+ disk on your Linux system without additional software. Or maybe you will need to install some additional software. That depends on what was included in the installation. The same is true for APFS formatted disks – install apfs-fuse to read these. There is also a Paragon product for Linux that allows Apple disks to be mounted.

If you want to read either HFS+ or APFS disks on a Windows systems there is third party software you can get to do that. For HFS+ disks, install HFSExplorer, Paragon’s HFS+ for Windows, or Mediafour’s MacDrive. For APFS disks you can buy “APFS for Windows by Paragon Software“. The MacDrive package can also be purchased to read your macOS drives on a Windows system. The article “How to Read a Mac Formatted Drive in Windows: 6 Methods” covers these and more.


There are four different filesystems common to Windows – FAT16, FAT32, exFAT, and NTFS. The exFAT filesystem was created in 2006 for use with USB flash drives and SD cards, so it is not directly associated with a version of Windows.

Reading a drive formatted in any of these filesystems is easy on your Mac. Just plug the drive into your Mac and it will mount it. If the drive is formatted with FAT16, FAT32 or exFAT data can be read as well as written to the drive. If the drive is NTFS, data can only be read. If you want to write to an NTFS disk, then purchase either “Microsoft NTFS for Mac by Paragon Software” or “Microsoft NTFS for Mac by Tuxera“.

Making it easy

Usually, we know in advance where we are going to want to use an external drive. The simplest thing to do is to format the drive for use across as many systems as is possible. That means that for cross-platform compatibility, the best filesystem to use is FAT16, FAT32 or exFAT. Both FAT16 and FAT32 are readable on Windows, Mac, and Linux without any additional software needed.

The exFAT filesystem can be accessed by the Mac without additional software. Linux systems will need exfat-fuse, but that is easily installed.

Most Thumb drives or external disks come pre-formatted with FAT32. That makes them useable anywhere out of the box. The only reason you would want to go to exFAT is if the data you wanted to store on the media was larger than 4 GB. FAT32 has a limit of 4 GB on files. With exFAT, files can be up to 16 EB in length. That is 16 Exabytes or 1018 bytes (see “What Do Those Terms of Storage Mean?” for more on data storage) – sufficient large for any storage need.

Formatting Media on Your Mac

Screen Shot 2019-03-28 at 3.51.16 PM

External media can easily be formatted (these examples are on macOS High Sierra 10.13.6) on your Mac. Connect the drive to your Mac and open Disk Utility (Finder ==> Go ==> Utilities ==> Disk Utility). On the left side you will see all the connected external drives listed (red arrow in image above). Choose the one you want to format and then click on the Erase button (orange arrow in the image). NOTE: Formatting a disk permanently erases all data on the disk!

Screen Shot 2019-03-28 at 3.51.42 PM

This will drop down a window that allows you to give the drive a new name and pick the format you want used on the drive.

Screen Shot 2019-03-28 at 3.51.53 PMIf you click on the Format window, a drop down menu will appear giving you a list of the format options available to you. While the Mac lists MS-DOS (FAT) this is really FAT32. You also have the option of formatting a drive as exFAT.


Disk Filesystem Summary

Filesystem Native to Journaled[1] Max File Size When Introduced
ext3 Linux Yes 16 gigabytes 2001
ext4 Linux Yes 16 tebibytes 2008
FAT16B (BigFAT) DOS 3.1 of later No 4 gigabytes 1987
FAT32 Windows 95 or later No 4 gigabytes 1996
NTFS Windows NT or later Yes 16 exabytes 1993
exFAT Windows CE 6.0 No 16 exabytes 2006
HFS+ macOS 8.1 or later Yes (as of 2002) 8 exabytes 1998
APFS macOS High Sierra (10.13) or later No, more modern methods 8 exabytes 2017



  1. A journaling file system is a file system that keeps track of changes not yet committed to the file system’s main part by recording the intentions of such changes in a data structure known as a “journal”, which is usually a circular log. In the event of a system crash or power failure, such file systems can be brought back online more quickly with a lower likelihood of becoming corrupted.

What Websites Know About You

Tech TipsWeb Tools – I wrote about using the privacy web tool WEBKAY for the first time (“What Can Websites Find Out From Your Browser?“) in July of 2017. While I was out walking today I was listening to an episode of the “Mac Geek Gab” podcast. They mentioned using WEBKAY and I thought it was time to revisit it.


Screen Shot 2019-03-19 at 6.21.21 PM

What WEBKAY (What Every Browser Knows About You) does is to analyze your brower’s settings. Just open in your brower and you will see a report displayed of what any website can find out about you! Among the datapoints displayed are:

  • your location (using your IP address)
  • the type of hardware the browser is running on
  • the operating system and version
  • the browser and version
  • what browser plugins you have installed
  • your public IP
  • your Service Provider
  • Your download speed
  • some of the Social Media sites you are logged into

While WEBKAY may not give as much detail in their report, they do provide suggestions on how to mitigate some of the findings.


Screen Shot 2019-03-19 at 6.19.30 PM

Another Web Tool that you may want to try is Panopticlick ( created by the Electronic Frontier Foundation (EFF). When you get to this site, click the “TEST ME” button.

This is meant as a wake-up call to users as to just how much their browsers are revealing.


Screen Shot 2019-03-19 at 6.47.23 PM

Yet another web tool is BrowserSpy ( BrowserSpy can tell you much more information about your browser and system, but you have to individually select the test (there are more than 70 to choose from) to be run.

Become More Productive on your Mac with File Tags – Part 2

Tech Tips – In Part 1 I talked about how tags can be added to files on your Mac. In Part 2 I will look at how you can use those tags to become more productive. NOTE: The following examples are done in macOS High Sierra 10.13.6.

Using tags with the Finder

Screen Shot 2019-03-14 at 4.41.38 PM

The easiest way to use tags is with the Mac Finder. First, we need to make sure that tags are enabled in the Finder. Open a new Finder window, then click on Finder, then Preferences.

Now select the third tab “Sidebar”. Make sure that the checkbox next to “Recent Tags” is checked.

Screen Shot 2019-03-14 at 4.37.46 PM





Now click on the second tab in the Preferences window, “Tags”. This window allows you to select which of your defined tags you want to show up in the Finder Sidebar. 

You can also drag any tag you want to add to the Favorites to the space at the bottom. I have not found this to be very useful.

Screen Shot 2019-03-14 at 4.55.22 PM



Now close the Preferences window and look at the bottom left of the Finder window. You will see several tags listed and at the bottom of the list “All Tags. . . “.

Screen Shot 2019-03-14 at 4.56.26 PM

If you click on the “All Tags…”, a new column will appear in the window with all of the tags listed. If you now click on a tag (in my example ‘:Star Wars’), then every file with the chosen tag is displayed in the larger window to the right. What makes this powerful is that it doesn’t matter where the files are physically located. Every file with that tag on your Mac and on iCloud, regardless of which Folder they reside in, will be shown.

This provides you with a very powerful way to search your entire Mac for files. If you have tagged your files, you will be able to find them regardless of where you have stored them.

More Power With Smart Folders

Using Smart Folders can give you even more power. Using the technique with the Finder above you can only search based upon one tag. If you use Smart Folders you can search on as many tags as you want.

Screen Shot 2019-03-14 at 7.06.53 PM

Go to Finder ==> File ==> New Smart Folder. This will open a window like is shown above. Now you can begin to specify the search criteria for what will be shown in your Smart Folder. At the far right side next to the ‘Save’ button click on the ‘+’ sign (Blue arrow above). This will open a space where you can begin to specify the search criteria. Click on the ‘Kind’ or ‘Name’ button noted above (Red arrow).

Screen Shot 2019-03-14 at 7.26.35 PM

A drop-down menu will appear. Click on ‘Other…’ at the bottom of the list as indicated by the Red arrow.

Screen Shot 2019-03-14 at 7.09.32 PM

This will bring up a long list of search attributes. If you scroll down the list you will find “Tags”. In the example above I clicked on the checkbox to the right side so that Tags will now appear in the short attribute list. I also clicked on the line ‘Tags Tags associated with this item’.

Screen Shot 2019-03-14 at 7.30.13 PM

Once I click on ‘OK’ that first search criteria will be set. I then chose ‘contains’ and entered the first tag to search for ‘:image’. I can add another search criteria by clicking on the ‘+’ indicated by the Red arrow. A search criteria can be removed by clicking on the ‘-‘.

Notice that when I click on the ‘Name’ button now ‘Tags’ (Orange arrow) appears in the list. I can now use this to pick a second or even a third tag to search on.

Screen Shot 2019-03-14 at 7.37.33 PM

In the example above I have selected three different tags as my search criteria – ‘:image’, ‘:scifi’, and ‘:star wars’. The resulting 48 items shown in this Smart Folder are all files on my Mac that have those three tags set. These items can be physically stored in any folder on my Mac or my iCloud drive.

What this means is that as long as I am very conscientious about adding tags to files, it doesn’t really matter where I store the files.

Screen Shot 2019-03-14 at 7.47.13 PM

I can then save these Smart Folders by clicking on the ‘Save’ button at the top right. Note that in addition to being able to name the Smart Folder and pick where it is going to be displayed, I also have the option of including it in the Finder Sidebar.

A further advantage of using Smart Folders is that since they are Virtual the same content can appear in more than one Smart Folder. This allows you to sort your files in many different ways without having to move or make aliases for files.

In Part 3, I will talk about tagged files in iOS.

Become More Productive on your Mac with File Tags – Part 1

Tech Tips – I am always looking for ways to become more productive on my Mac. Before I get into how tags can make you more productive, I think that I need to explain what tags are.

What are tags?

Tags were first introduced in macOS Mavericks. As the name implied, tags allow you to add one or more ‘tags’ to any file. These seem a lot like ‘Labels’, but there are a couple of major differences. First, you can apply more than one tag to a file or folder. Second, you can search and sort your files and directories by tag (that will be covered in Part 2).

How to tag a file

So now that you know what tags are, how do you add them to a file? There are actually multiple ways.

Screen Shot 2019-03-12 at 12.33.10 PM

First is adding tags to files as you save them. In any App when you go to save a file, you not only get the opportunity to set the file name and location, but you can also add any tags to the file. In the above example, I am saving the file “Sources for World War II Info and Photos” from within MacDown and I have added the two tags ‘:wwii’ and ‘:web’ to the file.

I use the convention with my tags of always beginning them with a colon and making them all lower case.

What if you already have files? There are three easy ways to add tags to an existing file.

Screen Shot 2019-03-12 at 12.47.01 PM

First, you can use the Finder to browse through your files and find the one that you are wanting to add a tag to. Once you find it Control-Click on the file. That will bring up the window shown above. Note that towards the bottom is “Tags…”.

Screen Shot 2019-03-12 at 12.55.23 PM

Click on “Tags…” and that will open the window shown above. Here you see any existing tags for the file and you can freeform type in the dialog box the name of a new tag to add. In the above example the tags ‘:blog’, ‘:wwii’, and ‘:bookreview’ were already attached to the file. I typed in ‘:s’ to start to add another tag. As you begin typing in the tag if a match is found to an existing tag it will automatically show up in the dialog box. In the example above seven tags are shown that begin with ‘:s’. I can either click on one to choose it, hit enter to choose the highlighted tag, or continue typing in the tag name. You can continue to add tags until you are finished. This method allows the selection of multiple files and adding the same tag(s) to all the selected files at the same time.

Screen Shot 2019-03-12 at 1.05.48 PM



A second way to add tags is through ‘Get Info’. Control-Click on any file and in the Menu you get (see second image above) the option of ‘Get Info’ will appear. If you click on that, then a new window with information about the chosen file will appear.

At the top of this window is a dialog box where existing tags are displayed and where new tags can be entered.






Screen Shot 2019-03-12 at 1.12.15 PM

A third way of adding tags is by opening the file in an App that supports Apple’s Document menu. At the top of the window will be a small icon to the right of the file name (pointed out with the red arrow in the image above). If you click on that icon a drop-down menu will appear that both shows existing tags for the file and which allows you to enter new tags.

In Part 2 I talk about how tags can be managed and how they can be used to improve your productivity.

Have You Ever Wanted to Search for a Mac App?


Tech Tips – Have you ever wanted a new App for your Mac but was not sure if such an App existed? Or perhaps you do not know the exact name of an App. MacUpdate may be the answer to that problem. MacUpdate, as the name implies, is primarily a source for keeping track of the latest updates for your Mac Apps. Per their website:

MacUpdate simplifies finding, buying and installing apps for your Mac.
Search over 40,000 Mac apps. Buy apps for 50% off at MacUpdate Promo.
Use MacUpdate Desktop to perform 1-click installs of apps you find on

If you follow them on Twitter (@MacUpdatePromo), you will get a tweet each day for every App that has been updated in the last 24 hours. I follow them and I get 15-25 tweets from them each day.

Screen Shot 2019-02-20 at 2.13.41 PM

The other way you can use MacUpdate is to search for Apps. Just enter what you want to search for in the search window at the top of the page and a list of Apps meeting your criteria will be listed.

In the example shown to the left, I searched for “ebook”. Notice that you see the rating of the App, the number of downloads, and the price. As you can see as well you have filters at the top of the page that you can use to narrow your search. Click on any entry in the list and you can install the App.

Today is National Clean Out Your Computer Day

Clean out your computer day

Tech Tips – As the name implies, this is the day to take a little time and perform often much-needed cleanup on your computer. As the site says:

Over time, files and programs that are unused on your PC clog the memory and cause confusion during retrieval and use of other data. They may also slow down your computer.  The second Monday in February, Clean Out Your Computer Day, is the day to spend time with your computer!

I posted “TUNEUP YOUR OS X MAC – PART 2” a few years ago which outlines ways to free up space on your hard disk. Those suggestions are still valid today. Take some time and clean up your Mac’s hard drive.
