Should You Update to MacOS Catalina? Or Wait? Or Not At All?

Should you update to MacOS Catalina or wait or not

Wondering if you should update to MacOS Catalina or not? Are you not sure if you’re truly ready to update and install MacOS Catalina? Perhaps you have a critical app or two that you know aren’t supported by Catalina, or maybe you’re hesitant to update because your current Mac system is working just fine for you, or maybe there’s some other reason you’re wondering if you should or shouldn’t update to Catalina.

If you’re not sure whether or not you should install MacOS Catalina, or you’re thinking of holding off on MacOS Catalina for a while, or even ignoring it entirely, we’ll discuss those ideas and present some alternatives here.

With every major new MacOS update, some users end up wondering if they should bother updating to the latest version of MacOS or not, and MacOS Catalina 10.15 is no different in that regard. But MacOS Catalina is different in that it no longer has support for 32-bit apps, and no longer has iTunes (instead it’s replaced by a series of apps to serve the same purpose), and those changes are different from other recent MacOS software updates. So what are the options? Let’s review some of the choices available, but ultimately it will be every users own decision to make on whether or not to update to MacOS Catalina now, later, or never at all.

1: Waiting Until Critical Apps Updated to 64-bit

If you have any mission critical apps that are 32-bit, you’ll likely want to hold off on MacOS Catalina until those critical apps are updated to be 64-bit, or until you find a replacement app for them.

You can find all 32-bit apps on a Mac in System Information tool as shown here if you aren’t sure.

If you aren’t sure whether or not a particular app will ever become 64-bit, your best bet is likely to contact the developer of that application directly, and inquire with them.

2: Waiting for MacOS Catalina 10.15.1, macOS 10.15.2, macOS 10.15.3, or later

While many users report MacOS Catalina works great for them, there are others who report the initial macOS 10.15 release is still fairly buggy.

There are mixed reports that the first release of MacOS Catalina 10.15 has some bugs which can impact various users to varying extents, with issues impacting things that worked fine with prior macOS versions. Reported issues include wi-fi difficulties, external device incompatibilities, problems with network sharing, problems with various apps not working (many likely related to 64-bit requirement), some users are finding the new security mechanisms to be annoying, amongst other possible bugs, complaints, and opinions.

If you’re not concerned about being on the bleeding edge, then you can always wait for a future point release software update.

You can always wait to install Catalina when one of the point release bug fix updates becomes available, whether that is MacOS Catalina 10.15.1, or even MacOS Catalina 10.15.2, MacOS Catalina 10.15.3, MacOS Catalina 10.15.4, or MacOS Catalina 10.15.5 (or maybe even later, depending on the updates schedule).

There’s nothing wrong with this approach, and many cautious Mac users do will wait until later more refined versions of system software are available before jumping in.

Any future bug fix and point release updates for MacOS Catalina will arrive to Macs that are running prior versions the same way that the initial MacOS Catalina download has arrived; through Software Update and the Mac App Store.

3: What About Skipping MacOS Catalina Entirely?

Is your Mac working great for you exactly as it is right now? If MacOS Mojave, macOS High Sierra, MacOS Sierra, or even an earlier system software version, is working fine for you and your Mac workflow, then you can always consider just staying put, and ignoring MacOS Catalina entirely.

This is a particularly valid approach if you rely on some 32-bit apps that you know will never be updated to 64-bit, or require some extensive upgrade that you’re not ready for. If you’re going to lose access and functionality of critical apps to your work, perhaps avoiding MacOS Catalina is a reasonable solution for you.

You’ll obviously miss out on any new features within the macOS Catalina operating system, as well as some stricter security measures available in Catalina, but for some users that’s a reasonable trade off to maintaining their currently working system as it is.

Some users may end up avoiding and skipping MacOS Catalina entirely, or using the earlier possibility of waiting for a later macOS 10.15.1, 10.15.2, or even 10.15.5 point release update.

If you’re considering skipping Catalina, keep in mind that Apple typically releases major security updates to the two prior MacOS releases, suggesting that MacOS Mojave and MacOS High Sierra will likely still receive critical security updates, even now that Catalina has been made available. Accordingly, if you stay on MacOS Mojave or High Sierra, be sure to install those security updates as they become available.

4: Want to Try Out MacOS Catalina Without a Full Commitment? Consider Dual Booting

Want to dip your toes in and just try out MacOS Catalina to see what’s new, while preserving your primary MacOS installation? You can do this easily with a dual boot environment thanks to the new APFS file systems.

If you aren’t entirely sure you’re ready to commit to upgrading your primary MacOS installation to Catalina, then you can give it a test by dual booting MacOS Catalina and MacOS Mojave (or High Sierra) using APFS volumes as discussed here. You will absolutely want to backup your entire Mac before attempting this procedure.

That particular approach obviously requires an APFS file system, which means you wouldn’t be able to do it with earlier macOS versions.

Ultimately whether or not you update to MacOS Catalina right away, wait, or never update at all, are entirely a matter of personal choice, so do what works for you.

Are you deciding to update to MacOS Catalina? Are you holding off? Are you going to wait for the first point release bug fix update, the second, or ignore it entirely? Are you going to try out Catalina with a dual boot environment to see how it works for you? Let us know your thoughts and opinions in the comments below.

    How do you out iTunes lib on an external disk?

  2. TD says:

    Very disappointing that Apple is making such a drastic change to no longer support 32 bit apps. I guess Mojave is my last update. I can always install a Linux VM I guess, but what a hoop to go through just to keep a good app that is 32 bits.

  3. Bob K says:

    My MacBook Pro is running on Mojave. Because of the limited size I put iTunes on an external drive and works well both on Mojave and previous OS. I talked to Apple Care and they told me that going to Catalina OS should work. The (Should) bothered me. I use Time Machine with hourly updates and restores have work in the past. Before upgrading an OS I create new backup on an empty drive for double safety. Any advice would be welcomed.

  4. Opinionated says:

    My opinion? Don’t install MacOS Catalina.

    Look at this article, others, it’s obviously not up to par.

    Abundant evidence to not touch this thing with a 10 foot pole. Never update to it.

    Apple leadership has abandoned the Mac, and it shows in the hardware and the software.

    What does Apple stand for anymore? It used to be products that “just worked” and worked great. How would you answer that now?

    And let’s not ignore that Apple is also making deeply political decisions that have consequences to people around the world, by removing apps that are considered undesirable by certain governments. You may say, who cares? But what if an app you use is considered undesirable by a government? Will Apple remove that too? What does Apple stand for today?

    You know it’s bad when even the “Everything Apple is Holy” crowd are saying this is bad:

    Heck no. Not ever.

    I wasn’t going to upgrade my MacBook Pro right away but I’ve been using the developer betas on my iMac all summer and ultimately decided to upgrade the 2018 MacBook Pro as well. So far I haven’t had any major issues.

    I have 2 Macs; an i-Mac and a MacBook Air. I installed Catalina on the MB Air but plan on holding off on the i-Mac as it is my main computer and I want to see if I can resolve the issues on the MB Air install. The only issue I’ve found so far on the MB Air is playlists that did not migrate, even though the titles of the playlist did. I’ll update this later.

    • Jeff B says:

      Should have mentioned in my last post… Before I made the 1st post I tried the suggestions mentioned in the article above, to no avail.

      I have since gone into the i-Tunes app on the i-Mac and exported to the desktop, the playlists desired on the MB Air. I then did an AirDrop of that file to the DeskTop of the MB Air, and from there, imported it into the Music app on the MB Air. And it works flawlessly from there. But really ? Do we need to do these band-Aid patches to the Mac OS on all upgrades ?

    The problem I have run into both in the past and very recently with Sierra is that if it proves necessary to re-instal the OS, it is not easy to acquire a download of an earlier version.

    Most recently (in trying to remove a persistent fault) I was advised by Apple chat to reinstal the OS via the Recovery mode, only to find that instead of Sierra, Mojave was installed. But this installation has provoked a new fault with Apple Mail and a complete OS re-instal has not cured it.

    I think that Apple is far too prescriptive over the OS; people should be allowed to make their own choice, not dictated-to. Also much greater stability is needed; an OS should be usable for at least 5 years before it demands upgrading.
