Samsung Evo ssd slow speed in Mac | Tom's Hardware Forum

Thanks so much. It is most likely something wrong with the app, in the past I got much faster with the same app on a older version with the same Mac. Sign up to join this community.

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. An utterly unfair comment.

Apple Support pushes anyone to update the moment they call in with issues. Very arrogant in nature. Any performance hits lies solely on the developer.

How to fix USB 3.0 External Hard Drive Slow Speed

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….

In their upgrade instructions Apple advises backing up your system. Backing up has been an established practice for decades. 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. 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.

Though your remarks suggest that you did not. 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. This is exactly how I feel. I am so happy someone just said what I was trying to say. Apple community seems to have a bunch of Apple fans who get really angry if you say any bad thing about Apple. Everything is really really slow.

I trusted that Apple new what they were doing with Mojave It was supposed to make our computer better, and not this piece of trash that it is right now. Mojave only works properly on an SSD. If your iMac has a mechanical hard drive, or a Fusion Drive, it works poorly. You should revert to High Sierra, or whatever version of the macOS you were using before upgrading.

You could replace your hard drive with and SSD, if you can afford it, and are capable working on the iMac, or know someone who is. Otherworld and iFixit have how to videos for working on iMacs. Samsung SSDs are often on sale and you can pick up an inexpensive external drive case. Otherworld frequently has them on sale. Mojave automatically converts the file system to APSF. But it works fine on an external SSD drive. They launch almost instantaneously. Your answer to everyone, which you repeat over and over, is that Mac users should have backed up before upgrading so they can revert from the broken Mojave OS.

Got it—thanks. How to go backwards is of no interest to me because my customers require Mojave due to security concerns, and how pretty the multicolored spinner is in dark mode is irrelevant. I upgraded to Mojave from OS 8. My Mac Mini started running slower a month after I upgraded to Mojave. After rebooting from a SuperDuper! Then I used SuperDuper!

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 , the graphics says it is supported. Running Mojave and mouse is tripping up or freezing.

Regards, amr. 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. 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. Still, I really like dark mode in Mojave. 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. 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.

2. ‘Having an external monitor plugged into your MacBook will slow down performance.’

Which means no hard drive gets routinely connected to their computer, even when one is available. And most critically, rebuild disk directory with Diskwarrior. Not yet. APFS is proving more difficult than most of us would have expected. Expect to have to pay for the upgrades when they come. Neither is Drive Genius. If you are concerned about this issue, you would be well advised to put off upgrading to Mojave on an APFS volume. MacBook Pro. WI-FI: hardware not installed.

Fact or fiction: What does (and doesn't) actually speed up your Mac

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.
