This bug extends to the Storage module under Sensei’s Hardware sidebar, where the Benchmark tool bizarrely prompted us to manually select a writeable volume-despite already having permission-then erratically displayed real-time read/write results. On the iMac and MacBook Air used for testing, the app rarely displayed every local volume, and even when it did, capacity gauges were empty across the board. A left-hand sidebar provides one-click access to four built-in Utilities (Optimize, Uninstaller, Clean, Trim), along with shortcuts to display more detailed Hardware particulars (Storage, Graphics, Battery, Cooling).Īlthough the Dashboard view is a sight for sore eyes, Thunderbolt-attached Drobo and RAID storage devices made Sensei behave schizophrenically. ![]() Underneath, sections are grouped by RAM, processor, graphics, and storage MacBooks also display battery gauge, health, and time remaining. The main window provides an overview of your Mac hardware, with model-specific details including serial number, manufacture date, and identifier across the top. Hardware that third party developers can release OS X support for.Sensei is a feast for the visual senses, packing a ton of hardware data inside an attractive, well-organized user interface. Means of enforcing security, but also a way for Apple to control what Have been modified, Yosemite will no longer load the driver. System are unaltered by a third party, or approved by Apple. Kext signing basically works by checking if all the drivers in the (A kext isĪ kernel extension, or a driver, in Mac OS X) More about Trim Enabler for Mac:Ībout Trim in Yosemite In OS X 10.10 (Yosemite),Īpple has introduced a new security requirement called kext signing. So, if you're using a DIY SSD, Trim support is tricky in Yosemite because of recent modifications to kext security management that affects Trim support. This is not relevant if you're using an Apple installed SSD or SSD that doesn't require 3rd party trim support for optimal function. So choices using Yosemite are, reduced security and potential system update issues or, a SSD that doesn't require Trim support. Apple changed kext signing in OS X 10.10 such that kext singing must be disabled to use applications like Trim Enabler for trim support. Please detail working hardware/software configurations and strategy/schedule as well as outcomes.ģrd party SSDs for the most part don't have trim support in Yosemite without kext signing security tradeoffs. I'm also considering turning on Trim Enabler periodically, then off and reenabling kext-signing to avoid issues with until (if) Apple restores TRIM support to hardware and software devs. ![]() So far, because of this article, I'm considering a SSD with Sandforce or equivalent active garbage collection. I'm hoping for strategy / options to work with SSDs that recommend or require Trim support. Trim Enabler author says using Trim Enabler by turning off kext signing is cracking a walnut with a sledgehammer. If you bought a SSD that needs trim support ( at time of writing, all SSDs benefit) such as the Samsung 840 Evo, there are many reported issues when performing PRAM reset and potential future system update conflicts in addition to the current security tradeoffs (see below). Whether this is vendor lock in or not, it's made upgrading a headache. Unfortunately Apple has decided to create kext signing in Yosemite that creates issues for SSDs that require Trim support for optimal function and longevity. Before reading this long question, please note that it is mostly outdated in light of the more recent developments reflected by the top answer.
