Backup your Mac and Windows 10 partitions on an external SSD drive using Carbon Copy Clone to backup/restore the Mac partition - and backup/ restore your Windows partition using AOEMI partition assistant and AOEMI back upper. The overheat problem will go away if you keep the power supply plugged in all the time ( I have a theory why - but I could be wrong.) The bottomline is the Samsung Evo NVME drive is upgradeable on the MBPr mid 2014 + Bootcamp.after about two weeks of messing around with the apple's road blocks, it finally works ! I cannot stand the site of the Apple young engineers, whose mission in live is to put up road blocks to keep Apple products artificially high cost - instead of competing on the high quality and innovative products. I live in Silicon Valley and I am an automation engineer (not a software developer). I'm happy to report that I have finally been able to upgrade my MBPr mid 2014 A13 with the Samsung 960 Evo NVME PCIE M.2 SSD + High Sierra + third party adapter board. I'm still investigating on how to either downforce PCIe to 2.0, either insure better signal quality to make the SSD work with 2015 MBPr 13' and 15'. The MBA (even 2017) and MacMini 2014 being stuck to PCIe 2.0 due to their Broadwell 5xxx CPU, they don't have this problem. They add a connector and complexity to the signal path, so they lower the RF integrity and compatibility with the higher speed of the PCIe 3.0 signals (8Ghz vs 5Ghz for PCIe 2.0). Those adapters are not designed to handle PCIe 3.0 speeds I guess. To me, it's a timing or signal quality issue due to adapters (Sintech or other) between Apple 12+16 and M.2). Sometimes, the NVMe drive work, but mostly they fail to be recognized. * : The problem with the MacBook Pro 13' and 15' early 2015 seems not to be insurmountable. MacBook Pro 13'-15' early 2015 : doesn't work yet* MacBook Pro retina 13'-15' mid-2014 : doesn't workĬompatibilty with non-Apple NVMe drive, (Samsung ), to this date the tests I have done yet are : MacBook Pro retina 13'-15' late-2013 : doesn't work It is to be noted that Transcend announced some PCIe SSDs (probably AHCI) for every PCIe macs, the transcent Jetdrive 820 (but only 2 lanes and price not yet available) :Ĭompatibility with Apple NVMe drive : (like those found in 2017 iMacs) Compatibility with AHCI PCIe drives : (ex.
