My IMac (iMac (Retina 5K, 27-inch, Mid 2015)) is suddenly taking up to 2 minutes to boot up.
I ran etrecheck today and there were several diagnostic problems reported.
I hope someone here can look at the report and explain what is going on - and how, if poss, it can be cured.
iMac 27″, macOS 10.14
Well, for a start, your hard drive is underperforming:
Performance:
System Load: 1.16 (1 min ago) 1.06 (5 min ago) 1.05 (15 min ago)
Nominal I/O speed: 0.04 MB/s
File system: 18.39 seconds
Write speed: 78 MB/s
Read speed: 84 MB/s
We have a 2011 entry-level 21.5" iMac with the same drive specs (7200rpm on a 3GB/sec SATA bus) and our drive runs about 25 percent faster than yours in the same test. However, it also takes well over a minute to fully boot. I doubt with the pro Apps like the Adobe stuff you will see fast boots without a solid-state drive.
I would uninstall TechToo Pro or at minimum, set it to run on demand instead of running in the background. In the infancy of OSX, third-party tools like TechTools Pro, Onyx, Cocktail, and Disk Warrior were indispensable. Today the macOS is so highly evolved that those could now be interfering with elegant automated maintenance routines built into the system. I stopped using TTP and Onyx when I bought a Mac running os 10.6 Snow Leopard in 2008 and have found I do not need them any more.
That could contubiute to the sub-nominal drive speeds reported.
You may wish to test again with all the externals drives disconnected in case one of them is contributing to the issue.
From Diagnostics, the fact that so many Apple systems are behaving badly makes me suspect a interference with system function from one or more of the system modifiers the report flagged.
Do you have something stuck trying to install? Lots of RAM is getting use by a installer process:
Top Processes Snapshot by Memory:
Process (count) RAM usage (Source - Location)
installd 1.20 GB (Apple)
mds_stores 800 MB (Apple)
EtreCheckPro 720 MB (Etresoft, Inc.)
Finder 260 MB (Apple)
sandboxd 243 MB (Apple)

Removed all external drives and ran etrecheck - improvement in performance
The instald 1.20GB no longer appears.
So I shall only use an external when I need it (Time Machine is now on all the time).
Hi,
Seems you have 32bit applications which don't work on your iMac. You'd better delete them first.
And start up in Safe Mode then normal boot could solve the issue.
Start up your Mac in safe mode - Apple Support
Activity Monitor can pick up background processes if you insure AM's "View" option is set to "All Processes."
That is from High Sierra but tI looks much the same in Mojave. See:
View information about Mac processes in Activity Monitor - Apple Support
It is possible the installer shut down since the test.
Hi kaz-k,
OP is running Mojave. 32-bit apps should not be an issue. I have dozen on my 2017 iMac with Mojave and have no speed or other issues.
I'll put TTP on 'demand', disconnect the externals and re-test.
As for the installer - there was nothing being installed that I know of. How can I check?
Will report back.
Activity just now - see attached screenshot.
I'll then post this morning's etrecheck - all external drives off
Etrecheck this am
iMac taking 2 mins to start up and other problems
