I am looking for a laptop to run Catalina and to buy some time before the new generation of ARM based Macs hit. I have a 4GB 2011 MBA that is now not OS supported beyond Yosemite. Use mostly for office tasks and web surfing. I found a mid-2014 MBP 13” 2.8 i5 16GB 512GB 80 Battery Cycles for about $375. One or two small dings, but mostly clean. Battery change if necessary is a little bit of a pain compared to non-retina, but this seems like a deal! What do you all think? Would I get a few years before Apple makes this processor obsolete? Or should I look for a 2015 or a newer used non-retina Air? Can I run Catalina on this as compared to Mojave? Thanks.
