  • I upgraded and regret it badly my Mac mini is now so slow and to be surw it was not hardware I put windows 10 on a partition incredible it’s 3 times faster than Mojave and app open up quick.

    And their beta version have updates each week or so using up my gb limit for what each update is worse than the other
    I understand it’s a free update yet to roll back to Sierra is a night mare

    On top of this many none apple apps are out of date in most cases hard to find none billable updates

    If you thinking of installing majove do not it’s beta but even windows do not release basically none tested systems

    Shame on you apple I have be a fevent Mac user since 1985 and this is the worse ever system




  • I’ve been working on Macs for 20 years. My summation is that when you upgrade to Mojave the apfs conversion is jacked up. I have been backing user data up, reformatting HDD (or ssd or whatever) to HFS+(deleting the container also), installing Mojave and then migrating data back over. I know this is an hours long process but you are wasting your time otherewise.




  • Everything has slowed since installing Mojave on my mac book pro. Pages and Word documents take forever to open, start up takes five-six minutes. I’ve done all the cleaning and clearing possible and am beginning to think a RAM upgrade may be needed. i have four gigabytes of memory available.




    • You definitely need more RAM. If your MacBook Pro is old enough to have only 4MB of RAM, it is probably upgradable. Check Otherworld Computing for available upgrades. Your Mac is probably an older “unibody” model; to replace components all you have to do is remove the screws in the bottom to access the RAM, battery and hard drive (and SuperDrive). An SSD upgrade will also improve performance substantially. OWC has kits for those tasks, as well as instructional videos to show you haw to do the job. Check their weekend Garage Sales for good prices on parts.




  • Mojave slowed down my Macbook Air big time.
    I downloaded ‘CleanMyMac’ and after using it my Macbook Air is now running beautifully.
    It was well worth the purchase price of €89.95




  • You know its funny how the majority of these help sites that I’ve landed on are essentially the same thing as going into an apple store, by which I mean they are pointing the finger at you and assuming that your mac needs an upgrade to fix performance issues (aka it’s not our fault, Mojave is fine).

    I don’t know how else to say this…MY MAC WAS RUNNING FINE before I installed Mojave. The performance is now sluggish at best and I’ve even lost a good amount of responsiveness during basic system operations such as opening and closing finder windows. I should’ve went with my gut and just left it alone instead of trusting that apple would release a stable build that actually improves more than hurts your system. That’s what I get for wanting to try out something new SMH…




    • Did you back up your system before upgrading? If so, you can downgrade easily enough. Though you may need a Mojave system to reformat your hard drive back to HFS+, as the APSF file system introduces a number of complications and older versions of Disk Utility can’t handle it. High Sierra might work; it is APFS compatible, too, but I haven’t tried it.

      I’ve said this before, but the APSF file system does not work well on mechanical hard drives. It was designed for SSDs. I have it installed on an external SSD and it works very well, accept for some software incompatibilities, which is to be expected. Installed on an external HDD, it runs poorly, which is to say I know whereof I speak. Though technical reviews of APSF have also pointed this out.

      Sorry for your trouble. But you should have looked before you leaped. You bear some responsibility here, whether you are willing to accept it or not. The information was out there for anyone to read. This very blog has done a good job of pointing out the issues. Personally, I never install a macOS upgrade on my work system. I clone it to an external drive (in this case, several external drives) and upgrade the clone to see what issues I may run into. While my main system remains with a viable version of OS X.




      • “But you should have looked before you leaped.”

        An utterly unfair comment. Apple Support pushes anyone to update the moment they call in with issues.

        And exactly how does the average user ‘look’ at their system performing before updating?

        ‘Cloning’ is rarely a viable means for the average person. It’s like telling a poor person “just get rich” as a response. Very arrogant in nature.

        Any performance hits lies solely on the developer. No update should ever degrade performance and if there IS to be a known performance hit, then the OPTION to upgrade should be clear and not buried in some legalize or blog that the average person would never see and updating the OS should never be the first step when calling in for support….yet this is not the case.




        • “Looking before you leap” means backing up your system, whether with a clone or with Time Machine, or, preferably, both. In their upgrade instructions Apple advises backing up your system. If the “average” user can’t be bothered doing this, even though Apple has made doing so drop-dead easy, then, simply put, they deserve any trouble they encounter with an upgrade. Backing up has been an established practice for decades. It’s not new. Nor is it difficult to do. Time Machine is automatic. All you have to do is plug in an inexpensive hard drive and designate it for backups. The Mac OS has long automatically offered to choose a new drive for Time Machine if you don’t already have one set aside. Apple doesn’t want you to miss the opportunity to do so. Blaming Apple is no substitute for doing your own due diligence. And it serves no purpose other than providing some catharsis for the complainant. It fixes nothing. Apple is not responsible for the precautions you didn’t take, especially as they make it so easy to do the bare minimum.

          Actually, you don’t say whether you backed up or not. Though your remarks suggest that you did not. It’s true that Apple Support often recommends an upgrade. Along with reinstalling the OS this is their fall back position when they don’t have a real answer for a reported problem. They can be faulted for this, as they have trapped many an unsuspecting user with unexpected changes to their system and apps. Still, backing up is part of the procedure of doing an upgrade. If you skip it, you are begging for trouble. Ignorance is not bliss.




  • I upgraded to Mojave from OS 8.5 and startup was slow, logging in out between users was slow, and waiting for desktop icons was slow too, and opening anything…nothing worked, zapping pram, resetting SMC..deleting start up itemes etc…and then I figured it out after a couple of hours of research and trying different things…I got rid of my Avira Anti-virus free program I installed…and now my mac is fine!




  • My Mac Mini started running slower a month after I upgraded to Mojave. I ran First Aid on my internal HDD and it failed.

    After rebooting from a SuperDuper! clone on an external HDD, I reformatted the internal drive and reinstalled a clean Mojave install. Then I used SuperDuper! to clone my latest back up on to the internal HDD. Now everything seems to run twice as fast!




  • Please, after upgrading to macOS Mojave last week, my MS word and Adobe cannot open, it is spinning the whole time…frustrated, any help asap.
    Mac Pro Mid 2012, the graphics says it is supported.




  • Please, after upgrading to macOS Mojave last week, my MS word and Adobe cannot open, it is spinning the whole time…frustrated, any help asap.




  • Running Mojave and mouse is tripping up or freezing. Help! Memory is adequate for what I’m running (Adobe CC). I don’t have any heavy doc opens.




  • after installed the Mac OS Mojave , my Mac book pro seems work very slowly , how to recover it , and there is a way to restore my Sierra …
    Need your help asap .
    Regards,
    amr




  • I have a Mac Pro 2013 model know what I notice the fan is running a lot faster now I wish I could revert back to The way it was I haven’t found a solution




  • Since the upgrade to Mohave my MacBook Pro runs out of memory , even without using any apps.




    • Open Activity Monitor and check out the “Memory” tab. I had an app that had issues during the upgrade process that caused it to get stuck in a loop and gobble up more and more memory. I killed the process that was causing the problem and everything one fine.

      I checked and found the vendor knew about the problem and had an update to fix the problem.

      Now, everything is wonderful, except I can’t decide which model of the new Mac Mini to order. Of course, since I just got my property tax bill (with 4% a discount for paying this month), I really don’t have to decide which Mac Mini to order until I have the money for it (Christmas next month – no, Christmas bills in January – no, income tax anxiety and forms in February – no, Tax refund in March – YES, something to look forward to!

      Thanks for letting me vent! :)




  • Never upgrade to Mojave, enough said




    • Not that I disagree with you, but some people say that about every OS upgrade. Notwithstanding the complaints reported here, many sources give Mojave a thumbs up. For my part, a number of apps I depend on don’t run, or don’t run well in Mojave, so I’m only running it on a test platform for now. Maybe after an update or two I’ll take the plunge. For now I’m settled on Sierra. High Sierra has many of the same problems for me that Mojave does, by the way, so I’m avoiding it as well.

      Still, I really like dark mode in Mojave. More and more apps are adapting to it so I’m hoping things get better. As for problems, I’ve seen few of those reported on this blog. Nor have I heard widespread reports about them. So I suspect that many are limited to specific systems. Which suggests, as is often the case, that some computers were inadequately prepared for the upgrade. And as is also the case, many people rushed into the upgrade without backing up their systems first. Really, there’s no good reason for not having at least a Time Machine backup handy.

      Upgrading without a backup is such an old, old story that I long ago ran out of sympathy for those benighted souls who make that sometimes fatal mistake. Then again, time was most computers sat on or under a desk, so it was not difficult to keep it connected to an external hard drive for backup purposes. These days most people use laptop computers and reconnecting to a backup drive is a rule honored too often in the breach. Even though the cost of external drives has fallen drastically. Many Macs now have so few ports that people use them only for recharging the battery. Using a dongle or a dock to provide more ports doesn’t appeal to some folks. Which means no hard drive gets routinely connected to their computer, even when one is available.

      Still, I’m grateful in the end for early adopters who find many of the flaws in an OS upgrade. For my part I’ve cloned my system onto an external drive for the upgrade so I can test Mojave in real world conditions (real for me). So I’ll know what I’m getting into before I upgrade my working system.




  • And most critically, rebuild disk directory with Diskwarrior. Waiting for version 6 supporting APFS to upgrade from macOS 10.12 Sierra to 10.13 High Sierra or 10.14 Mojave.




    • There is no version 6 of Diskwarrior!




      • Not yet. APFS is proving more difficult than most of us would have expected. It’s a big leap, so the utility developers are having a hard time upgrading their software. Expect to have to pay for the upgrades when they come.

        Despite several interim upgrades, TechTool Pro isn’t there either. Neither is Drive Genius. So, don’t hold your breath for DiskWarrior 6 or any other major utility. I expect they will get there eventually, but in effect it’s not unlike the jump from OS 9 to OS X, wherein we lost some utilities, like Norton, and gained others, like TechTool Pro. If you are concerned about this issue, you would be well advised to put off upgrading to Mojave on an APFS volume.




  • MacBook Pro. After uppgrading to Mojave I couldn’t access Wifi. I gott mesage “WI-FI: Maskinvara ej instllerad” which means. WI-FI: hardware not installed. I ended upp downgrading from timemachine backup .




    • Good man. Too bad more people don’t keep a backup so they can revert if they run into problems they can’t solve.

      That said, there are solutions suggested from back with Sierra: https://blog.macsales.com/38608-common-problems-after-installing-macos-sierra-and-how-to-fix-them. Of course if you can’t get on the Internet it might be hard to find these solutions, which are listed at several sources and seem to be standard troubleshooting solutions for WiFi problems. Essentially, worst case scenario, your WiFi settings have been corrupted and need to be replaced. Less seriously, your WiFi setting has drifted from your preferred network and may need to be reset; this is the simplest solution.

      Bottom line, WiFi issues are perhaps the most commonly reported problem with an macOS upgrade going back well before Sierra and would seem to be subject to the same solutions. The link I posted is for a Rocket Yard blog post; they cover macOS upgrade issues thoroughly, in my experience.

      Unfortunately, not every problem is amenable to a solution, which is why backing up before you upgrade is not only the best policy, it is the only policy. Anything less is gross negligence, in my opinion.




  • I am considering the change to Mohave. Recently changed to High Sierra. Very slow, music stops playing when system goes to sleep. Thank you to all that share their knowledge.




  • In regard to APSF, Mojave does indeed convert a hard drive. For my test platform I cloned the APFS volume to an HFS+ partition. It runs better there, though I haven’t done any benchmarks to compare the two.

    Also for testing purposes, I did a clean Mojave install on an external SSD taken from an older Mac that I got from Otherworld on sale. It’s only 64GB so I couldn’t put my primary system on it. But it does start up and run faster. I’m considering getting a larger external SSD so I can try my system with Mojave.




  • Mr. Nelson

    Thanks for the tip about this possibility. Since your posting seems to address mainly those folks with an HD for their boot drive, my understanding is that Mojave will now automatically convert not only an SSD but an HD to the APFS, at installation. Since they designed the APFS for SSD’s, not HD’s, this seems bound to cause problems. Regardless, before I do upgrades to the OS, I run DiskWarrior (DW) to make sure my directories are in the best shape. If necessary, I run DW after installation for the same reason. Alsoft, DW’s developer, says that Apple has finally released the full set of tech documents for the APFS (a *year* after they introduced it), so they presently are updating DW to work on the new file system. I for one have not, and will not, install an APFS-version of the OS until I have a version of DW that works on it.

    Cheers
