Hello, I'm wondering if anyone could lend a hand on an issue I am newly experiencing on my iMac. Lately, anything to do with the file system seems to be running incredibly slow. For example, moving files, deleting files, installing files, etc. Did a large transfer between my computer and an external hard drive the other day and it took nearly 12 hours for 1TB (lots of large video files). I tried to update my Adobe Photoshop/Premiere Pro/Illustrator - each one took nearly 45 minutes to install once downloaded. Updated pages/keynote/numbers .... downloads super fast. Installs took forever. I have boot camp with windows installed and I'm experiencing the same issue there, too. For example, I ran the Windows Update Assistant. It downloaded everything I needed very quickly, but the install process is taking forever. What could be causing this? Is there a way to fix without having to format the drive.... or would that even fix it? I'm running the latest MacOS. iMac 27" Intel Core i7 3.4Ghz with 32 GB of Ram and 1TB hard drive (which is only about 20% full). Thank you in advance!
