The ideal solution would be for you to take your iMac to an Apple store and have them replace the internal spinning-disk hard drive with an SSD and increase the RAM to 16GB, this would improve performance markedly.īeing realistic, the cost to have this done in an Apple store would be close to two thirds the price of a new iMac with SSD and 16GB memory already installed, and certainly more that the current value of the Mac. Lastly, whenever you upgrade a macOS, Apple’s Spotlight service needs to build a fresh index of the disk, and if you use Time Machine to back-up your system as well then Time Machine also needs to scan the entire disk to build a new backup.īoth those processes will take up to 48hrs of continuous on-time to complete and until those two initial processes have finished running your Mac will run extremely slowly.Īs GreeniusGenius asked in his reply “Do you have an SSD?”, from your description of the problem I suspect your answer is no. Gradually those background processes complete and this releases more RAM memory for your application to use. The combination of a slow internal hard drive and limited RAM are the principle reasons for the poor performance you are now experiencing.Īt wake-up from sleep Monterey runs dozens of background processes, wake-up from power-off is even more demanding with hundreds of background processes running, this is why performance improves after the Mac has been switched on for a while. Your iMac has most likely a spinning disk hard drive, which is going to be very slow, and with only 8GB memory available for Monterey and InDesign to run in then InDesign will have to use virtual memory on your hard drive in order to operate.

Adobe recommend that InDesign requires a SSD drive and a minimum 4GB RAM, but 16GB is preferable.
