Here is the screenshot of TRIM enabled on 10.10.3 with NVRAM/PRAM intact WITHOUT setting kext-dev-mode=1 to disable kext signing. In case you had the wrong IOAHCIFamily.kext file after enabling kext signing like me and got a block sign when booting, you can always follow CindoriвЂ™s guide to reverse changes done by trim enabling software. With that file in place, you can disable TRIM enabler and reenable kext signing again after making sure that you have the original IOAHCIFamily.kext file restored.

I recommend the вЂњEven Better Method (No kext-dev-mode required!)вЂќ in which you download the zip file containing the Apple signed file `AppleDataSetManagement.kext` which is new in El Capitan and unzip it in `/System/Library/Extensions`.

I found a guide that showed me how to enable TRIM to on 10.10.3 to support TRIM without disabling kext signing or patching the system file IOAHCIFamily.kext by just adding one Apple signed system file AppleDataSetManagement.kext from El Capitan. If you donвЂ™t want to upgrade and still want to stick with 10.10.3. They include a command trimforce to make this happen. The big takeaway here is that if you are running a third-party SSD as a boot drive, and you do have TRIM enabled, then you need to take steps before upgrading to Yosemite to make sure that your drive will continue to be accessible after the upgrade.Mac OS X 10.10.4, which is released on Jand the upcoming 10.11 вЂњEl CapitanвЂќГўв‚¬ЕЅ will allow the user to enable TRIM on third party SSDs. Some SSD drives, such as those supplied by OWC, do not require TRIM to be enabled because they have the feature built into the drive, and are as such unaffected. I just had a grey screen and a dead system.' All of the earlier versions of OS X didnt have the kext signing feature but somehow we managed and the rest of the OS X security features are still in.

Is this what Apple wants to be known for? At the very least the installation should detect if an appropriate SSD is present before attempting to install and notify the user if thereвЂ™s a problem. As to 'sacrificing the security features on mac,' keep in mind that the TRIM Enabler/Yosemite conflict started with Yosemite and only the security feature introduced with Yosemite is affected. For professional environments and pro video it is even more troublesome andВ it puts vital data and creative projectsВ at risk. 'To have an official installation of OS-X simply stop working when upgraded from Mavericks to Yosemite is unacceptable for any user. 'I have to say IвЂ™m extremely disappointed by Apple with this,' writes Andrew Reid on the DSLR filmmaker site EOSHD.

The blog post also outlines how users locked out of their Macs following an upgrade can get back into their systems. This is the only alternative for enabling Trim for the moment.' 'But I have been unsuccessful in creating aВ less invasiveВ method to enable Trim, as all of AppleвЂ™s AHCI SATA drivers are closed source and undocumented, which makes it impossible for me to create my own Trim driver and get it signed. 'It is important to note that disabling the kext-signing to enable Trim is best described as taking a sledgehammer toВ crack a nut,В and for most users it will not be worth it,' writes Cindori Software. However, if you rely on third-party SSDs, it's your only hope. The Trim Enabler software has been updated so that it can disable kext signing, but this is a global setting, and disables an otherwise useful security feature. This is a means of enforcing security, but also a way for Apple to control what hardware that third-party developers can release OS X support for.' 'If they have been modified, Yosemite will no longer load the driver. 'Kext signing basically works by checking if all the drivers in the system are unaltered by a third party, or approved by Apple,' wrote Cindori Software on its blog.
