Bruce Johnson, I thought I should tell you how things have moved on for me. I never said I could afford anything like $649, or even $400! I'd never even heard of Fleabay before, but I joined and found out that they had no Macs near me. I assume this is because I'm not in the USA. Wow, I was using an old nickname for E-Bay in that email Next, I bought a cheap MacBook Pro 13" (mid 2012) with 8Gb and a 500Gb HDD from eBay for less than the equivalent of $267. I was very happy with this, but after about two weeks the screen started flickering like mad, as well as blanking out and turning green! I don't think this had anything to do with me installing "Patched Sur", because it didn't happen immediately after that. That indicates a loose screen cable connection, which it appears you discovered! After this, I thought I should buy another, cheaper MacBook Pro 13" (mid 2012) and see what I could do with it. I bought one for just under the equivalent of $151 also from eBay, which was showing the screen saying that it couldn't find an operating system. After it was delivered, I soon had Catalina installed on its 500Gb HDD. I quickly found out that this MBP (mid 2012) has only 4Gb of RAM, the very reason why I bought my second recent Mac, although it's upgradedable! It seemed to work more slowly than the other MBP. Slower RAM and only 4GB of it will do that every time. Later on, I bought a Philips 00 screwdriver and removed the back of the MBP with the faulty screen. I also have a new set of Torx screwdrivers. I had a look round and checked that the Philips 00 screwdriver would also unscrew the bracket holding the RAM in. You do not need to unscrew any brackets to replace RAM in MacBooks with replaceable RAM! This is OWC’s RAM replacement video https://www.youtube.com/watch?v=Vh9hazA5hRo for that model. All you need to do is remove the 10 screws holding on the back; the ram has spring clips holding it in. replaced the back of this MBP, but I lost one screw and another one wouldn't go in! The next thing I knew, I found that the screen was no longer giving me any problems! This is still the situation a few days later and I'm typing this message on it! https://www.ifixit.com is your go-to guide for all of this. All of their Mac disassembly guides are excellent. I”d take another crack at your 2013 If you ever need to work on things with teensy screws, I ABSOLUTELY reccomend getting a piece of egg-crate foam like this https://foamonline.com/wp-content/uploads/2020/01/Egg-Crate-Foam.jpg You can usually find a chunk for free. This keeps all the teensy screws accessible and contained. The best part is that I can dig into each well with my fingers and pick up one screw without disturbing any og the surrounding wells…whenever I work on a Mac or PC I can put the case screws into the wells in the same pattern they go in, put the screws for a subassembly together, etc. It’s saved my butt a thousand times over. I've made up a music track in Logic X Pro, and made a 1080p video on my Nokia 2.3 phone and MBA. I've also made a 1080p video on my Nokia 2.3 phone and my first MBP after the faulty screen problem disappeared. I'm now planning to upgrade one of both of my MBP computers to 16Gb and an SSD. Both excellent and worthwhile upgrades. I hear that some people can even upgrade the CPU on these 2012 MBP models from i5 to i7, so I'm considering having that done, but I don't think I could do it myself. Some people like to use the Davinci Resolve software, but I'm not sure what it can do which iMovie can't. Does it do CGI or what's so special about it? My ambition is to upgrade my MBP 2012 computers to be more powerful than models from years later. My ultimate goal is to create a clone of an Apple Silicon MacBook, using an iPad, a Raspberry Pi, or a Banana Pi computer. That…won’t work very well. Sure the iPad, RasPi is ARM based, but the M1 is more than just the SOC Apple uses (which, BTW is a LOT more powerful than any of the chips in the aforementioned devices.) -- Bruce Johnson University of Arizona College of Pharmacy Information Technology Group Institutions do not have opinions, merely customs -- You received this message because you are a member of the iMac Group, a group for those using Apple iMacs and eMacs.
