What To Do About Those Mojave “App Is Not Optimized” Messages

After updating to Mojave, many Mac users see a message saying that an app they are trying to use needs to be updated and won't work with future versions of macOS. By future versions, that means the next major update of macOS, probably coming in late 2019, not minor updates. Before then, you can update to a newer version of that app, or find an alternative app to use in its place.



Apple Link: 32-bit app compatibility with macOS High Sierra 10.13.4 and later.

    Nice concise presentation re: 32 bit apps. Is that rumor true that the next version of macOS is nicknamed “Death Valley” because it kills all the 32 bit apps? ;)

    Ron: Funny. (But for those wondering, of course not).

    Can you delete apps directly from the System Information list ? Thank You.

    Don: No. You uninstall apps in LaunchPad, or using the instructions from the developer if the app didn’t come from the Mac App Store.

    Thanks – this is a great help, BUT…. with many of these ‘not optimised’ messages, I can’t even figure out which app the message refers to and I have no idea how to contact the developer as Apple suggest. I have only watched your video once, so if this is all covered already, then please accept my apologies.
    Thanks

    Mick: The messages say the name of the app right in the message.

    Thanks Gary, very timely advice as always. One question: my wife and I get these periodically on our Mojave iMacs that identify a “process” or the like, with a fairly abstract name, not an easily identifiable app or anything we are knowingly using (or need). Is it best we just let things go as is and then let the new OS next Fall deal with it, send it to software purgatory so to speak? Thanks.

    Michael: Search for the process name in Google. You usually come up with some clues that tell you which app the process belongs to pretty easily.

    H iGary, I’m still using CS6 (because I don’t want to use the Adobe’s cloud version of the app. I have a 2017 macbook pro running with Mojave, and I have received those messages for InDesign, Photoshop, and Illustrator. Do you have a suggestion for an app that will run in future OS versions that is similar to InDesign? Thanks!

    10 months ago

    Bobbi: Why not InDesign? I mean if it is the best app for the job and you are using it professionally, then why the resistance to paying for Adobe’s software? That is especially true if you are using not one, but three of Adobe’s apps? Then it looks like a pretty good value.

    Hi, Gary. Love your articles. I have one question that is a serious concern. Hope you can help. I’m using Microsoft Word 2011 on my desktop iMac. I periodically get that message. Will I always be able to use Word on this computer? So far everything is cool. Hope so for the future. Thanks, Gary.

    Hi, Gary, you hit the nail on the head and I should have included this reason in my first email…I am retired now with just one or two freelance clients a year. 95% of my InDesign use is for my own “dabbling”…ie, creating greeting cards for friends’ birthdays, creating a children’s book about learning colors (not for sale, just for my friends who are grandparents), etc. So, I can’t really afford to pay Adobe’s costs…and I agree, if I were earning more professionally I would be open to that!

    Bernie: You can continue to use your old copy of Word on your Mac for now. The message is just a warning. But you’ll need to update to a newer version of Word before you update to the next major version of macOS, which will probably be out in the fall. Word has had many updates since 2011.

    Bobbi: Your choices then are to find alternative software in the Mac App Store or elsewhere, or to never update your Mac past Mojave. Of course if one day your Mac fails or you simply wish to get a new one, then you’ll be on the latest OS and be forced to move on from the old software.

    Gary, thanks, I will continue to look for an InDesign-like program…maybe shareware…if it’s OK I’d like to suggest that to “Bernie” who asked about his 2011 version of Word. I would have also had to update for the same reason, but was guided by a friend to a shareware program called “OpenOffice” which is free, and runs similar and compatible versions of Word and Excel…again, I don’t use these programs “professionally” and they work great for my purposes. Thanks btw for your quick responses!

    Great information. Thank you Gary. I’ve deleted a rant about Apple! I’m with Bobbi Sloan- retired and use programs for hobbies.

    Hi Gary, I have looked at the list in system report of applications and it says “no information”. Any ideas Love your posting by the way.

    John: Maybe try a reboot and then wait for a while on that screen. I’ve never seen “No Information” appear there. Of course, it is only a convenience, so you may want to decide not to worry about it.

    Hi Gary,
    Thanks so much for the info. I am now armed with the information and know what to do.
    Much appreciated

    What about GarageBand supposedly not being compatible? Why would Apple not just update that too instead of giving me an error message about Mojave? I mean, a conflict between an Apple OS and an Apple app, why wouldn’t it just work?

    8 months ago

    Micha: Not sure what you mean. GarageBand is certainly compatible with Mojave. They updated it often in fact. Are you maybe using a very very old version of GarageBand? At some point they had a major change, many years ago, and allowed people to keep the old version and also the new. Perhaps you have the old? The current version of 10.3.2. YOu can get it for free from the Mac App Store.

    Hi Gary. I used Wine to get an old Windows app to run quite well on my Mojave Mac. But, I get that message that it’s not optimized. I’m confused as the Wine app is 64 bit and it shows my “processed” app as 64 bit in the Mac’s System Report. Thanks for your insight.

    Alan: I’d ask the developers about that.

    One of the apps on my Mac that was only 32-bit according to System Information was Audacity. So I went to their website to download and install the latest version, which was 64-bit. I tested it out, and it worked fine. It can be launched in a number of ways, including via Launchpad. But the odd thing was that, when I went back into About This Mac > Software > Applications then Audacity no longer appeared in the list (even though it is there in my top-level /Applications folder. Puzzling!
