Mac High Sierra Takes Long Time For External Hd To Mount

Step 3: Start the Installation of macOS Sierra on the Non-startup drive. Launch the Installer from /Applications folder. Click Continue. Check the non-startup drive that you can install Sierra on (usually, the installer will display the default target for the installation of macOS Sierra as the startup drive (Macintosh HD). Hi there, I have a a external 1TB Segate HD that I with my MacBook Air. After upgrading to macOS Sierra, it refuses to mount and so is invisible to Finder. Disk Utility detects the drive as initialised NTFS and says all the space has been used. I tried first mounting it through disk utility, but it did nothing.

In general, it takes about 30 seconds for a Mac machine to fully start up, depending on the hardware configuration though. For example, Macs with flash storage (solid state drive) load much faster than those with HDDs (hard disk drive). Years back, ZolloTech did a comparison test on the startup time between an SSD-based MacBook Pro and a HDD-based one. The MacBook with SSD only took 22 seconds to fully start up while the other was 49 seconds. So, it’s pretty clear that a MacBook with an SSD is a lot faster than a traditional HDD.

We thus highly recommend you upgrade the hard drive if your old MacBook is very slow on startup. How to check if your Mac is with an HDD or SSD?

Now let’s go back to the topic of this post. If your MacBook Pro takes more than 30 seconds to boot, or even minutes, beware that your Mac may have performance issues. We’ve found 6 possible causes and related fixes to boost MacBook startup times. Some fixes work better than others. We’ll show you all of them so you can determine why your Mac is slow on startup and figure out the the best tune-up solution. You just installed a newer macOS If you just updated your MacBook Pro to latest High Sierra ( if you haven’t done so), you probably have noticed that your Mac takes longer to fully load up and respond to general tasks. This is normal because some apps (especially Spotlight, and Photos) need to re-index or update its data. How to fix: keep your Mac on for 24-48 hours, and restart several times after that.

If that still doesn’t help, you may need to enable TRIM (more below). Why this helps: apps like Spotlight and Photos usually need quite some time to re-index data. For example, Spotlight has to scan the internal hard drive and reindex all the files, likewise, Photos (formerly iPhoto) may update the while photos library as well. The process could take a significant amount of time to complete, and lots of system resources are required for the task. Once completed, your Mac’s overall performance would improve automatically. If your MacBook Pro (with SSD) still runs slowly on startup, consider enabling TRIM and the whole process takes only a minute or so.
