Slow to boot and slow running IMac Retina 5K 27-inch 2019

Uninstall Trusteer per their directions , then run etrecheck again to see what chaff it left...

Start with this...

Safe Boot, (holding Shift key down at startup), does the problem occur in Safe Mode? Could take 10 minutes or more.

Safe mode attempts to repair Disks & clears lots of caches & loads safe Drivers, & prevents loading of 3rd party extensions, so if Safe Mode works try again in regular boot.

You can use Drive DX to possibly get a better view of Drive health…

Run another EtreCheck report so we can make sure you removed all of Trusteer.

At one point, Trusteer engineers participated here due the the large number of Mac users struggling with Trusteer/Rapport. At that time it typical only affected Safari performance. Then IBM bought the company, their enginnering presence here disappeared, and things got worse, going system-wide.

several of the hihg CPU usage flags relave to Spotlight and its indexing routines. You can reduce Spotlight's workload by going to its setting and limitng wha tis indexes. About 80% of what is indexes does not need indexing.

Remove the following items from your User Login items:

• Amazon Music
• Apple Software Update

Those have to phone home and can cause slow startups

+1 on Trusteer being removed. To learn why please continue reading:

Trusteerr is considered malware by most experienced users on these forums. Mac OS is catlike in that it cleans itself, Mac OS does not benefit from nor does it require any of the following types of third party apps:

·      Antivirus Apps

·      Cleaning Apps

·      Security Apps

·      VPN Apps

·      Maintenance Apps

What these types of apps do is the exact opposite of what users want. They make Mac OS slow, appear buggy, can damage Mac OS and sometimes create unwanted behaviors. In short, they are really bad news! All that Mac OS needs in order to remain secure and fast is to keep Mac OS up-to-date and restart the computer about 1x per week and that's it!

So the first order of business for your computer is that you need to locate the developers. uninstall instructions for Trusteer and please uninstall it. Because Trusteer is pretty nasty stuff it tends to leave parts behind after being uninstalled, a testimony to how poorly written the app is! To fully ensure you have uninstalled it please download the free version of FindAnyFile directly from the developer. Then have it search your system for the following:

Okay, when you ran the DriveDX it only tested the small SDD portion of your Fusion Drive. I should have advised you to ensure that the HD portion of your Fusion Drive should be tested and not the SSD. This is critical as the SSD rarely fails and the HD portion of the Fusion Drive is almost always the culprit of failure!!!!!!!!

If you are confused, that may be because you don't know what a Fusion Drive is. It was Apple's "budget" response to speeding up a traditional HD system between 2012-2019 Macs. A Fusion Drive is made up of a very small SSD and a traditional HD that are fused together with software. As mentioned the SSD's tend to be reliable but the HD's tend to fail anywhere from about 5 years old or anytime after that. This is why it is critical to run DriveDX on the HD alone. If for some reason you cannot figure out how to do that, please take the computer to your local independent Apple Authorized Service Provider to be professionally diagnosed, DO NOT take it anywhere else like the local PC repair shop ONLY take it to an Apple Authorized Service Provider!

RAM

It looks like you had enough RAM at the time that you ran the report, in spite of the report's claim that applications were using a lot of RAM.

There was 10.01 GB that was completely free, and another 7.93 GB holding cached data that could be dumped, on demand. So, plenty of free RAM. Swap used was 0, indicating that you had never run out of real RAM and forced the computer to simulate extra RAM, at the cost of much, much slower accesses to the disk.

If you do things like running heavy Photoshop workloads (lots of "stacking" of layers or "stitching" of panoramas), running Windows inside of a virtual machine, etc., then you might want to run Activity Monitor and look at what the Memory section says while you are running the heavy workload. Otherwise it sounds like RAM is not the problem.

Virtual Memory Information:

Physical RAM: 32 GB

Free RAM: 10.01 GB

Used RAM: 14.06 GB

Cached files: 7.93 GB

Available RAM: 17.94 GB

Swap Used: 0 B

Startup Drive

If the internal drive is not actively throwing errors that crash the Mac, and cleaning up the software installation does not speed up the Mac as much as you want, you might consider getting an external SSD to use as a startup drive.

Details:

Your Fusion Drive has a very small SSD. Originally all Fusion Drives – including 1 TB ones – included 128 GB of SSD space. In Late 2015, Apple cut the amount of SSD space in 1 TB Fusion Drives from 128 GB to a miserly 24 GB, and from that point on, 1 TB Fusion Drives had only 24 – 32 GB of SSD space.

It is prime real estate, but there is not nearly enough of it.

An external Thunderbolt 3 / NVMe SSD will blow away that Fusion Drive – and my guess is that even external SSDs that use USB-C (USB 3.1 Gen 2) / NVMe or USB 3.0 / SATA could deliver better performance overall, since they will storing everything on prime real estate, not just a fraction of the stuff that could benefit from it.

Great, please let us know how the machine behaves after you have done the uninstall and run FindAnyFile.

Please attach the DriveDX report so we can go through it. Using multiple sets of eyes to get a thorough exam may reveal things you cannot see.

Hmmm, I don't see a problem there.:(
