![]() (As I can't check 13inch, for SMC I have no data, but your EFi BootRom will get an update if you install High Sierra at least. These versions should then still be available in or work with Yosemite, if you want to keep that system. You might still get the latest for your machine by installing a later version of macOS onto an external drive, which now should prompt an update of those components en passant. If you are already on the latest SMC version for your machine, it may be a hardware problem with your battery after all.Īs a limited workaround in general to get the latest versions of firmwares: Apple doesn't distribute these as standalone packages anymore, as the above (outdated) page demonstrates. Therefore it seems that you guessed at the problem and found bad advice on Apple's part on one page relating to version numbers that you read correctly. Either this update (1.7 in this case) was supported in Mavericks as well or I booted temporarily into a version of (Mountain) Lion on an external drive just to apply this update. My 2011s went from Snow Leopard straight to Mavericks. (That's what the binary identifies itself with at least) 2011MBP13.smc Version: 1.68f99Īs to the supported versions of Mac OS X form which to run thiese updaters: (Can't check 13inch now.)Įffectively Apple says per the table on its knowledgebase page: "Upgrade to SMC1.7" but meant to say 'upgrade to SMC1.6'? On a MacBook Pro 8,2 15inch Early 2011 the version number is 1.69f4. They seem to have switched the SMC version numbers around, wrongly. The right one for your model MacBook Pro 13inch 8,1 Early 2011. ![]() This update is recommended for MacBook Pro (Mid 2010) and MacBook Pro (Early 2011) 15 and 17 inch models. System Requirements: OS X 10.6.8, OS X 10.7.5, OS X 10.8.2 or laterĬontainin the actual files : 2010MacBookPro13SMC16, 2011MacBookPro13SMC16 This update addresses a rare issue on some Apple notebooks where a battery that has accumulated more than 1000 charge cycles may unexpectedly shut down or stop functioning. MacBook Pro (13-inch, Early 2011) MacBookPro8,1 1.69f4 (SMC 1.7)īoth of these packages have the same name without version numbers when downloaded.īoth seem to address the same thing or kind of problem: There seems to be a problem on the Apple KnowledgeBase page. If not, is there any other official word from Apple regarding the right number of the latest SMC update for this model? So i guess my question is: Has anyone with the same Mac model successfully updated its SMC firmware with version 1.7 (1.69f4) and can confirm that it is INDEED intended for this Mac model (MacbookPro8,1)? I have not yet attempted that as I'm aware of the risks and don't want to finish bricking my Mac with a wrong SMC firmware. With some more digging, I found that I COULD manually install an SMC update through an EFI command-line mode in rEFInd. Either that or Apple used totally inconsistent naming for the files and folder inside the package. ![]() That all seems to indicate that, although this update is listed on Apple's website as for the early 2011 13-inch MacBook Pro, the software inside is intended to use in other machines. This info was retrieved from the names of folders/files buried within payload files.
