My iMac is 8 years old, manufactured in 2014, purchased used, and I'm to a point now that working with it for photo editing at times boarders on maddening due to its slowness. I use this machine almost exclusively for PS and LR, and while on some days it seems fine, on others it seems that every adjustment I make triggers the spinning wheel that sits for well over a minute. I've spoken with Adobe support, and even after they assisted in making some settings adjustments to optimize speed, I'm still facing the same issue. I've also spoken to someone at AppleCare who was not able to offer any new informations. So, here's what I've done so far...

- Reinstalled LR and PS
- Created a new catalog in LR
- Optimized LR catalog
- Cleared cache in LR and PS
- Reduced the time when both LR and PS are open simultaneously
- Watched the Activity Monitor for CPU usage and Memory Pressure - this does show excessive memory pressure (yellow and red on graph) from time to time
- Scanned for Viruses and Malware

And here are the particulars of my machine...

iMac (Retina 5K, 27", Late 2014)
Processor: 4 GHz Quad-core Intel Core i7
Memory: 32 GB 1600 MHz DDR3
Graphics: AMD Radeon R9 M290X 2 GB
Storage: 1.12TB (320 GB available)

As you can imagine, I'd prefer to not buy a new machine, but at this point, I'm willing to bite the bullet if it will finally mean I no longer have to sit and watch that ball just spin and spin!

Thanks in advance for any help you can provide, which will be greatly appreciated.

Several months ago I finally decided to switch from film to a DSLR. The last stimulus check made it possible.

I wanted a D750, but that would have used up too much of the stimulus as I also had my eye on a newer wide to short tele zoom...the AF-S 24-85 VR. So I decided to go for the D610 which like the D750 was 24mp. I found one on eBay being sold by a pro who recently had it cleaned by Nikon and had less than 18,000 clicks...for $600 delivered.

I was very happy with it as it looked mint when I received it.

The D610 also has a built-in autofocus motor so it will work perfectly with older AF Nikkors and AF-D Nikkors many of which will save big bucks over AF-S versions. You can get a 50mm f/1.8D lens for $100 or less. I got a 50mm f/1.4D for $130 but that was a lucky buy.

Whatever you decide...happy shooting.

Well, you may be interested to know that:
Ivermectin was approved for human use in 1987.
The doctors who discovered Ivermectin won a Nobel Prize in 2015 for its successful use in humans to treat several devastating tropical diseases, including river blindness (onchocerciasis), strongyloidiasis, trichuriasis, ascariasis and lymphatic filariasis, as well as to treat less severe conditions such as head lice and scabies.
Ivermectin is also used in veterinary medicine to treat parasitic diseases.
