I have never heard of that, what's the % speed increase?If able to, reprogram the EPROM that governs SSD speed to maximize throughput beyond what the factory permits.
Never heard of it either, @Lomtevas has that ever been done before?I have never heard of that, what's the % speed increase?
There is a hidden switch in the BIOS chip established to deliberately keep SSD speed way down.Never heard of it either, @Lomtevas has that ever been done before?
Thats beyond my technical skill but that would be pretty impressive results.There is a hidden switch in the BIOS chip established to deliberately keep SSD speed way down.
Find and desolder with a hot air gun the BIOS Chip on the motherboard.
Use a BIOS flasher RT809F SOP8 adapter. Attach the BIOS chip.
Read firmware contents to find the two A7B5 entries.
download the 0.28.0 UEFITool.
Reverse engineer EFI image by replacing the BIOS chip's firmware with a modified - 3.0 GUID file. Replacing the A7B5 file changes chip speed. Replace the two A7B5 entries using the RT809F.
Write and refresh the BIOS chip. Resolder using sodler paste and a hot air gun.
Speed goes from roughly 1,362 MBPS to 2,800 MBPS.
Maybe because the newer macs are of a poorer quality and perhaps they have soldered on RAM and SSDs that fail. Perhaps upgrading an A1278 from between 2012 and 2008 will yield a better laptop?why would I need a faster Mac than what apple deemed appropriate for me?
The newest Apple Silicon Macs are very good. Haven't had any issues yet it seems (apart from the obvious software compatibility challenges in the beginning). The 2016-2010 Intel MacBooks were a whole another story though.Maybe because the newer macs are of a poorer quality and perhaps they have soldered on RAM and SSDs that fail.

Perfect disaster. $1,700 for an A-1990 15". Unit arrived with scratches and bald spots on the gray ink. Warranty was two weeks, and when I discovered this problem, the warranty expired.
Then the unit stopped responding three weeks after their warranty ran out. Apple replaced the upper case under a recall, but left the touch ID non-operational. Then, keys began to fling off, and a class action law suit gave a second upper case replacement.
OWC said their warranty did not cover any repairs and I could send the unit in for a price. They did not advise me of the recall and the law suit.
Use craigslist to get your macs, and get the older ones. Upgrade the RAM, SSD, and the wifi. If able to, reprogram the EPROM that governs SSD speed to maximize throughput beyond what the factory permits.

out of curiosity, what can they do being so old?no one can beat their $69 Mac mini 2012 price that works in 2023
and they stand by every used mac.
ebays can't promise this!
Lots of things!out of curiosity, what can they do being so old?
what can "what" do?out of curiosity, what can they do being so old?
Because Apple doesn't always (let alone often) know what's best...?why would I need a faster Mac than what apple deemed appropriate for me?
As a whole, 3rd party refurbishment is a gamble at best. Theres no real standards there, not much in the way of guarantees (part quality, repair quality, etc), no way to know if your unit just had a spit shine then price jacked up or had all sorts of things replaced with lord knows what, and in the case of certain parts from OWC like Storage/memory/Batteries, you learn that a lot are not super trustworthy when you go through thousands of them. I've used OWC parts extensively at all the service providers I've worked at and truthfully i wouldn't give them to my family, let alone an entire system that may or may not be using some of those parts. Their Battery and Memory-based products just are not good, and in the past have had some pretty serious and egregious amount of failures Better now, at least on storage/mem side, but also just get Samsung or Corsair or whatever and save the headache to begin with. They also truthfully charge too much relative to what else you can find elsewhere for parts and machines.Has anyone bought a used Mac from OWC? Are they OK to deal with?
