Too bad I found this post just few minutes ago (maybe that should be merged here): Then turn off again, open, remove superdrive, put caddy/HDD back, close, assemble superdrive on its external USB case again, etc etc etc… So I just gave up, opened my Macbook, got the Superdrive back in place, burned the iso on CD, booted holding the C key (no need for rEFIt/rEFInd) and after 10 seconds from Boot I had the new firmware running, gave it a test/check on sysPref. With all that I knew it would also not boot from an external CD drive as well. If your firmware is different you may have a chance though. I even got the USB recognised some times, but turns out that the Apple firmware my computer uses does not like to boot Legacy Linux systems from external drives. Everytime I created the bootable USB pendrive I tried booting with Command-C, alt(option), standard rEFIt/rEFInd and whatever I could think. Now to get that iso to an external USB, I tried using the Windows SSD Tool Kit, Universal USB Installer 1.8.7.8 and Universal USB Installer 1.9.1.6. So I got the R211m firmware which downgrades the SSD to 3Gbit/s which is the max speed for that Nvidia firmware anyways. My Mac has the infamous Nvidia MCP79 SATA controller that runs on 1.5Gbit/s(instead of 3Gbit/s) with the “normal” firmware. rEFIt is abandoned but still works quite fine on Macs, I just took the extra care of installing it manually, as advised on the rEFInd site (the installer may cause errors on some Macs). I was using rEFInd (a fork of rEFIt), but in the process I have tried both rEFInd and rEFIt but there was no real difference on the results. I am using Mountain Lion on a MacBook 13-inch, Aluminum, Late 2008 (MacBook 5,1). I spent a whole day trying this, hoping to avoid opening my MacBook again. I dont think this is missing anything, I did it quickly so let me know if you are having problems and I can try to help!įirst quick thing to say is that the method described above on the main post of this thread will NOT work for most people (including me). This puts the boot menu back to normal and your drive should also be updated. System should boot into the Linux Kernel and start the firmware image loaderīoot back into OSX and remove the EFI folder on the main OS drive and double check that the Startup Volume is the SSD drive (Settings - Startup Volume - verify what drive is checked) Using your keyboard arrow keys go to the right and select boot partition from USB “partition name” Once completed the drive will now have a bootable partiion along with the firmware image file needed for proper flashing Run the USB installer app on the Windows side, select Old Syslinux and select the ISO firmware file Plug in the USB drive and make sure it mounts into the VM or Windows machineįormat the drive manually via Windows Disk Utility (I prefer this over using the USB Installer app) On the Windows VM/machine download Universal USB Installerĭownload the rEFit tool, run it and install it on your machine, this is only needed temp, you can simply remove it once the drive is updated. rEFit - Download from (will only need this temp) Firmware download v211 for your respected drive model Windows Based machine for running Universal-USB-Installer-1.8.7.8 (a VM running on Fusion/Paralells is fine, even if its on the same machine that you are updating There was a post over on crucial forums with a similiar method, however it missed a key step that inlcuded the copy of the actual firmware image over to the drive. With FW211 there still are posts asking the same questions, so I put together a working solution that isnt that hard and I have verified works on my own systems. There are a few convoluated solutions floating around via searches and old posts. There seems to tstill be a lack of an official way to update our SSD drive firmware for Macs.
