MB Pro (Early 2013)
pretty easy guide. i replaced the left fan recently, so i decided to do the right as well since it had been making the same grinding noise, albeit not quite as loud. the fans themselves were pretty clean, i’ve typically use a blast of compressed air to dust them out about once a month over the almost 5 years i’ve owned this MBP.
i skipped steps 3-4-5. and using some of the comments as guidance i was able to take a few short cuts and have the fan replaced in about 20 minutes. powered up the MB without the back cover just to make sure the fan would spin, it did, checked to make sure everything worked, internet, BT connection, camera etc, powered down, screwed on the back cover and done.
awesome guide. i skipped steps 3-4. prior to placing the back cover on, i tilted the mac on its side and powered up to see if the fan worked, it did. powered down, screwed the cover back on and good to go. took about 20 minutes.
Installed/upgraded 4gb RAM to the system maximum 16gb and installed a 500 gb SSD today....DID NOT disconnect the battery cable....no issues at all when I powered back up. Then did a clean install of OSX Yosemite....next I used a time machine backup to put all my stuff back on the new HD. From start to finish it took about 4 hours. Macbook boots up right at 16 seconds now.
