Macintosh OS 10.15 "Catalina"

The upcoming Macintosh OS 10.15 "Catalina" will not run any older 32-bit applications. So now is the time to start taking stock of which apps you will need to upgrade/replace/abandon.

Microsoft Office 2016 has a free update to 64 bits.
https://support.microsoft.com/en-us/...64-bit-upgrade

Direct download:
http://go.microsoft.com/fwlink/?linkid=525133

If you want to know which of your apps are 32-bit only (and hence need to be updated or replaced to work under Catalina), you can use either or both of these free utilities:

32-bitcheck (free)
https://eclecticlight.co/32-bitcheck-archichect/
Check any, or all, folders of your choosing, and you can check just your apps. Generates text reports if you like.

Archichect (free)
Drag and drop utility that instantly tells you if any one particular app is 32- or 64-bit
https://eclecticlight.co/32-bitcheck-archichect/

Note that FreeOffice (mentioned in another post of mine) is already 64-bit!

This can be done with the built-in tools:

1/ "About this Mac"
2/ "System Report"
3/ "Software->Applications" (this will take a minute)
4/ click the "64-bit" column to sort by 32 / 64 bit apps.

True. In fact, it can be done several different ways, including with Activity Monitor. I just mentioned 32-bitcheck and Archichect because they are dead easy to use, very fast and convenient, and free.

Item 4 does not appear on screen in the OS 10.15 BETA version of About this Mac. Any 32 bit apps are disabled and may be hidden away but somehow are still shown in the Launchpad. Weird!

Not Weird at all, considering you are running a BETA OS!!!

Besides that, even if they are showing, they won't run in Catalina OS. Maybe they might even get around to sticking a warning flag up to let you know that if you try to open them, and are they still actually including LaunchPad???

The 32 bit apps don't show in the finder but are in the Launcher with a greyed out "?" overlaid. The 32-bitcheck app referenced in Mr. Singers post does not show any 32 bit apps on the SSD. I just thought it strange that the system still contained some reference to them.

I guess then, unless they change things from the BETA, that it will be up to the user to seek and destroy all 32-bit apps and any associated files to save wasting any hard drive space.

I assume that no Mac apps contain both 32-bit and 64-bit code so that old unused code would have to be removed to save space as some had to do back with the old surplus PPC/Intel code changeover years ago.

The Catalina BETA is still far from being in it's finished form. For one thing it's really slow, as they haven't even optimized things for best performance yet.

I'm sure that once Catalina is released that it will throw up some kind of notice when trying to launch 32-bit apps that they are deprecated. I also suspect that the Catalina installer will have some sort of warning that installing it will break all of your old 32-bit apps.

Personally, I've been advising people to wait as long as a YEAR after it's release before considering upgrading to Catalina, so that the app market can catch up to it. It may ultimately be that entirely skipping Catalina might be a good idea. We will have to wait and see.

I just wish Apple would stop their annual OS updates or at least slow down somewhat drastically and then concentrate with improvements and fine tuning.

Dream on....

Well, first, that's what High Sierra was supposed to be. And it seems quite fast and stable to me. (Assuming you upgraded to High Sierra via a clean install.)

Second, I think that overwhelmingly, if you ask folks, that they would like to see the Mac OS moving forward, not become stagnant.

Apple isn't dropping 32-bit support in Catalina capriciously. Users have clamored to be able to load up on RAM in their Macs for many years now. Apple is giving that ability to the folks who want/need that. And Catalina should be noticeably faster than past OS's. Users will like that too.
