Is NAS a solution for a super slow iMac?

I have a twelve month old iMac, running Catalina 10.15.2. I bought it when my 2012 Fusion Drive iMac ground to a halt, the spinning ball of **** dogging my every key stroke. When I migrated everything over, I did not use Time Machine, instead I dragged and dropped everything (which was a massive pain when it came to migrating emails).


It seemed fine for a while but eventually, many tasks, from start up to launching apps, to creating a new email etc, took an unreasonable amount of time. I took it into Apple, to the Genius Bar, where the woman acknowledged that, for a new iMac, it was remarkable slow, even taking into account my transition from Fusion to standard HDD.


She recommended starting from scratch and, again, carefully migrating files over. It seemed to work for a while but, eventually, the SBOH returned. I have disconnected all peripherals and the issue remains.


I have run Malware and Bitdefender. I cleaned up a bunch of things with Bitdefender, or quarantined them, although any thing suspect sat on an external drive.


My music all sits on an external drive, but my photos and vids all sit in Photos on the internal HDD.


Memory does not look to be an issue, but one thing I was wondering is, if I hooked up a NAS and moved things like Photos to it, would that help to speed things up?


One other consideration, I guess, is that I bought a super cheap version of Office 2019 (not subscription based) which I later found out is probably a third-party product, or whatever it's called. It's slow as a Datsun 120Y, but I suspect it's the iMac, not the software.


Any ideas or suggestions are welcome.


I'm really disappointed with this iMac and I've been in the Apple ecosystem since the 80s.

Well the primary problem is you bought a base model iMac that is intended for only doing e-mail, surfing the Internet and not much else. It is limited by it's hardware which is 8 GB of non upgradeable RAM and a glacially slow 5400 RPM HD. What many people that have similar issues do is to buy and external SSD and then clone their internal HD to the SSD and use the SSD as their boot drive and everyday drive. Once they have done this they re-format the internal HD and use it for additional storage.


Other than that I don't see anything wrong with the system. You may want to restart it (it's been six days) in Safe Mode to clear some caches especially after uninstalling BitDefender and also ensure you re-connect your Time Machine backup External Hard Disk as it's been awhile since it was backed up. However I don't suspect restarting in Safe Mode will make much of a difference but then again it might.


I think your best bet to get really excellent performance is to add an external SSD and that should transform it. If you would like suggestions about hardware and how to do the project we can help on that too.

I would recommend a Macsales.com 2.5” SSD ( you decide on the capacity ) and a macsales.com Mercury Elite Pro Enclosure. If you call and speak to them they will be happy to help. Tell them your plans and ask how the SSD should be formatted. Once the SSD and the enclosure arrive put the SSD in the enclosure (5 minutes tops!!!) and then using Disk Utility to format it. Once formatted download SuperDuper! And clone the internal drive to your new SSD with SuperDuper! Then set the SSD to be your startup dive in System Preferences and enjoy your new speedy computer.

I suspect the issue may be that you have bogged down your system with worthless software that makes it perform poorly. My hunch is based on what you have already stated, that you have Bitdefender installed on the computer which is 100% worthless and has a reputation for making Mac OS unstable and slow. Please do the following and we will look for obvious issues:


Please navigate to the Mac App Store or navigate to www.Etrecheck.com and download the free version of EtreCheck. Once you have you downloaded the app and installed it, please run the report and save it. This report will help us get a good idea what has been installed on your system and help us be able to diagnose what may be wrong.


When you have your report, you can attach it when you reply to this message and we can then review it and help you determine what is needed to get your system running well again. 


For instructions on how to download your EtreCheck report and attach it to your reply to this message please click https://discussions.apple.com/docs/DOC-250000211

You can use /Applications/Utilities/Activity Monitor.app to see what your system is running and what is taking up resources, i.e. CPU and Memory, you can click on the columns to sort in descending order to see what the hogs are. Sluggishness can be caused by something using up a lot of the CPU, or if you are short of RAM and the system is using Swap space on the hard drive when RAM is not sufficient.


You said that memory was not an issue, so how do you know this? Are you using any Swap at all?

Hi there, I thought I'd just follow up...


I bought a 1TB OWC Mercury Electra 6G 2.5" SSD and an OWC Mercury Elite Pro Mini enclosure. As you said, 5 mins to install the drive in the enclosure, then cloned the HDD using SuperDuper!. Booted from the SSD successfully. Fantastic! Back to the speeds of my old fusion drive. Thanks heaps for taking me through the process and, once again, apologies for my initial reluctance.
