Yah for memory upgrades for computers. Our Mac is about 4-5 years old now. It was really started to show signs of slowing down. It was much slower for me to process photos which was why I started working on batches of three at a time versus every day (there are other reasons too!). We bought the computer with only 1 MB of memory. That wasn’t going to do the job for us. We could have bought a new, faster, computer, but those are so expensive and we do not have the money for that right now. So, we opted for an upgrade in memory to help get the computer moving faster. I am pleased with the performance. It’s like brand new again!
