This applies to upgraders going from Mavericks to Yosemite with TRIM enabled. I had the impression at the time that only Apple Store SSDs would have worked with the MBPs and anything else was broken without 3rd party support and Yosemite wasn't supporting the 3rd Party SSDs due to kext signing. It's nice that TRIM is supported again, but during the time TRIM wasn't supported, it wasn't even near being the End of the World.Īpologies for that. There are no immediately noticeable symptoms of TRIM not being enabled, and some SSDs don't even need it. The only thing that broke was TRIM support, and that was hardly a disaster. That's a bit of an extreme alarmist statement."completely broke support" ? I do remember that disassembly was a PITA. I had forgotten the specs and I don't have the MBP anymore. For once HDDs were hard to find in PATA form by 2008 and 66 MB/s was slower than the best 2.5" HDDs. It was the switch from PATA 100 (running at 66 MB/s) to SATA II in late 2008 that made the use of the optical bay practical. late 2011 through mid 2012: SATA III & SATA III.early 2011: SATA III & SATA II (or III).late 2008 through mid 2010: SATA II & SATA II.Here are connection types of the two bays (HDD/optical drive): I had considered the idea until I heard that the DVD at one point was on SATA I and the hard disk was on SATA II. I think modern SSDs have their own built in methods of keeping themselves healthy and do not rely on TRIM as earlier ones used to. I've looked at the Samsungs but haven't bought any. I've looked into this and did not find a way to do this. Is there a way to enable trim on an external (samsung 1 TB) drive? El Capitan 10.11.0: Enable Trim safely using Disk Sensei!.Yosemite 10.10.3-10.10.5: Enable Trim safely using Disk Sensei!.Yosemite 10.10.0 – 10.10.2: Not supported (kext signing issues).Mavericks 10.9.0 – 10.9.5: No issues, use Disk Sensei.Mountain Lion 10.8.0 – 10.8.5: No issues, use Trim Enabler 3.Snow Leopard 10.6.8: No issues, use Trim Enabler 2.2.You should be OK if you're on El Capitan. In your opinion, is it worthwhile to dump that much money into this dinosaur?Īnother concern is that Yosemite completely broke support for 3rd party SSDs, at least for the earlier versions. I'm eyeballing an OWC 1TB SSD upgrade for $450. The battery is at 88% of its original capacity, but it's otherwise good as new. I have a first-gen 15" Retina MacBook Pro from 2012 (i7, 8GB, 512GB SSD). This thread has helped reassure me of that. But this laptop is too good for that kind of treatment. I'm usually of the mind that I need to stay in a frequent upgrade cycle to avoid losing too much value in the iterations. If anybody has found another brand that will work, I'd certainly appreciate a link so I can compare it to what OWC offers. It appears to be unique to the 15" MBPs from this time period. The SSD in this MBP is not a typical 2.5" laptop drive size/shape. I have searched somewhat extensively, but it appears that OWC is the only company offering an upgrade for this model. Regarding the SSD: Several people have recommended upgrading the current SSD with a certain brand. I don't think I'll need a new battery for at least another year, but it's good to know I can get one when the time comes. I did not realize that it could be replaced fairly easily and inexpensively. I think my main concern has been the battery. It really is a great machine even compared to the current models, which offer (to my knowledge) a relatively minor performance boost over this laptop-certainly not enough to justify the purchase price. Basic specs:ĭual display cards - Intel HD Graphics 4000/NVIDIA GeForce GT 650M 1 GB To clarify about my particular machine, it's the first MacBook Pro to have a retina display. I appreciate all of your different points of view.
