• 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.

  • 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.
