Is it the factory HDD? Did you install an SSD? Get Blackmagic Disk Speed Test from the app store and check the drives read/write performance. If it's a platter HDD your symptom points to it failing and will be to be replaced.

Likely the bottleneck of the 5400RPM drive. The newer OSs run really poorly on spinners.

You can run SMART Utility to verify if the internal drive is failing: https://www.volitans-software.com/apps/smart-utility/

Regardless even if it isn't, I would recommend fitting an SSD. If you don't much fancy ripping apart your iMac, you can plug one in externally to a USB 3 - SATA caddy and install the OS directly to there, and boot from that. It will vastly improve your system performance.

Love the thread! Still run mine daily

More info needed.

Fusion? 5400rpm/7200rpm? 21.5/27" model? How full is the hard drive? Ran Recovery over the drive?

sorry for the incomplete specifics--I am thinking this is a common malady thus common remedies... and so it seems...

the apple wizard guessed that is was all the software that I have in addition to the apple stuff ...I suspect we are all guilty of that..rather than spend a whole deleting, rebooting, etc with an apple tech( some of them are just brutal to deal with and none of it is quick ...hours)- I questioned or tried to get some prices etc for an ssd or fusion set up without success (no prices) but my guess is 600.00 parts and apple repair and a horrible in traffice drive 100 miles round trip to take and pick up..
anyone have any thoughts about the apple diagnostics?? that seems to be the next logical if I can get some conformation from you all.
I have ran the disk utterly several times in the last few months (3) I think all good...-I am not sure why apple insisites that we keep updating ios ...cept for the fact that more survielance stuff loaded in they alreay know I have wart in a funny place. odd, not funny. hd has plenty of room 70 80 % or more have all my stuff on

[doublepost=1547166800][/doublepost]thanx will look into that...surly some youtube info on that.thanks again
[doublepost=1547167135][/doublepost]sorry posted before I could clean it up fat fingers and not drunk- thanks all- ssd or fusion seems to be the answer the rest is unnecessary hassle that will lead to ssd or fusion I am guessing. which is what I guessed in the first place- sometimes these apple folks jerk you around unintentionally I am sure ...but still a hassle.

With the low price and easy installation of SSDs, there is no reason to consider a fusion drive. You can get a 5 year, 2TB for under $300 for the SATA buss —smaller is less expensive, of course.

Removing that spinner requires the OWC temp sensor whether you install a new drive of any kind or not.

A 2013 will not benefit from the 6x speed boost of a 970 EVO in the PCIe slot but it is less expensive than the NVMe 2 chips available from OWC. You must run High Sierra or later and there will be a wake from sleep issue unless certain Terminal Command is run. Otherwise, it will give you about 3x performance over an SATA III SSD, same as the OWC/Intel.

Here's the OWC NVMe 2 SSD. You don't have the clearance for the heat sink. Not really an issue in an iMac.

Your biggest bang for the buck is replacing the HDD in the SATA III position. Either way, you'll feel as if you have a new Mac.

Since it is 6 years old, consider replacing the NV RAM battery at the same time. Although a CR2032 battery does work, Apple recommends the BR2032, an industrial version with a wider heat tolerance (that's the only real world difference). A Mini with an SSD only runs cooler than an HDD or fusion drive so I see nothing wrong with the CR — but it's not my iMac. The BR2032 is readily available on Amazon.
