    Hi guys, what would be the simplest way to upgrade to Sierra? Just download it and install it? Would that keep the custom kexts, etc? Thanks!

    Hi guys, I am looking for the EmuVariable migration process so I can remove the EmuVariableUefi-64.efi driver. I think it was on the main post at some point but I cannot find it anymore. Would someone please post the process? Thanks!

    Hi guys- I got a new T450 at work. Anyone has installed OS X on this model or has any tips? Thanks, AJ PS: My T420 is of course doing great with El Capitan thanks to this thread.

    Hi guys- A couple of questions: 1. Any issues updating to 10.11.2? 2. I have noticed that with the latest couple of packs, sometimes when I do a shutdown, the system reboots automatically. Anyone experiencing this? Any ideas why? Thanks, AJ

    Hi- Anyone updated to 10.10.3? Any issues updating from App Store? Thanks, AJ

    @tluck- Well, I don't have an APPLE folder under /Volumes/ESP/EFI. Should I? Link you sent me says it's for Mid 2013 models, but in my "About this Mac" screen, it shows I have an early 2011 MacBook Pro. Is this what it should be? Yes, it shows on the app store updates list. I have installed the update several times but it doesn't seem to go anywhere... Thanks, AJ

    Hi guys- I have this EFI Firmware update I can't seem to be able to get rid off: MacBook Pro EFI Firmware Update 2.7. I have tried to install it and to hide update, but it is still there. Do you guys have it? Thanks, AJ

    I upgraded directly from the App Store and all worked okay. The install process created a new temporary entry in the Clover boot screen named something like "Install OS X" on my system drive. I booted from there and it continued with the setup process. After the install, it rebooted again and the temporary entry was gone so I booted normally... All seems to work fine, just the Display overrides were replaced...

    Hi tluck- So, do we need to create an installer USB or just running it off the app store works fine? Thanks, AJ

    Thanks tluck, I was able to finally get iMessage/Facetime to work. I followed the iMessage posting you mentioned, Step-5d, specifically following the excerpt below. After entering the values for ROM and MLB as described there, and making sure it was not changing between reboots, I got the contacting oracle support message (described in Step-8). I called apple with the code provided in the message and they unlocked my imessage without problems. ****************************** The official (new) method of injecting/specifying the ROM & MLB values for Clover is as follows: ROM: This will now be read from the last 6 bytes of the 'SmUUID' field. If you have nothing in the SmUUID field then Clover will try to use your BIOS's SystemId (see Part-2 of the guide) however, I personally think it's always best to override The BIOS (even if it does not suffer from the SId bug) and to use the terminal command 'uuidgen' to generate a new random value (See Part-2, Step 7, Path-C). Enter the generated UUID as the SmUUID value on the SMBIOS page. If this is a new OSX Install then you can leave it like that. If you want to keep you old ROM value then replace the last 6 bytes of SmUUID with the ROM value you were using before which is normally the MAC address of an ethernet port (usually en0). Note: It is important to understand that configuring Clover like this will cause your existing Hardware (Platform) UUID to change (if it's an existing install). Whilst this in-it's-self is not a problem it will change the identity of your system from your previous install which in-turn may cause some user profile settings to be changed due to the Hardware (Platform) UUID being used as a key value for storing critical OSX configuration against. MLB: This is now read from the 'Board Serial Number' field on the SMBIOS page, on a clean Clover install this is defaulted to Clovers own set value which is now black-listed on Apples systems. You therefore must replace this with your existing MLB value (on an existing install) or use your OSX S/N + Random Alpha / Numeric digits to make it up to 17 digits. ******************************
