TotalFinder, (my one MUST HAVE mod) is working fine on 10.10.4 using the latest version of TF.ĬAUTION: IF YOU USE ANY SYSTEM MODS (TotalFinder, cDock, Liteicon, Yosemite Revert, etc.
Read more about this SEPARATE PROBLEM UNRELATED TO THE LINUX PROBLEM HERE:įirmware update is provided as an ISO bootable CD image that will boot Macs or Windows PC., using a Linux micro kernel, that locates and updates the drive. This problem affects the drive regardless of OS, so highly recommended you update the firmware. The latest firmware from Apfixes this by periodically 'refreshing' all the data on the drive to keep the charge strong, even data that isn't accessed. This problem is not OS specific and deals with the actual physical nature of the drive itself. HOWEVER, there is ANOTHER issue with Samsung EVO related to reading data that is 'old' (not been accessed) where the charge may degrade, requiring multiple attempts to read the data.
Windows and OS X ignore this bit because as of now, they only support 'normal' sequential TRIM, so is unaffected BY THIS PARTICULAR PROBLEM. Not true, there are actually TWO critical issues discoverd so far with the EVO drives, one known problem, true, related to the drives having an incorrect bit set that tells the OS what type of NCQ queing command it supports, in which Linux attempts to implement and runs in to problems. Some users are insisting the problem is only with Linux, and you don't need a firmware update. There is a lot of confusion about the multiple issues with the Samsung and the need for firmware update.
IF YOU OWN A SAMSUNG EVO OR EVO PRO, 840 OR 850, be sure to install the latest firmware before turning on TRIM support Now, even though it's not instantaneous, I can actually say it 'pops up' as opposed to 'redraws'.Įnabled TRIM using the new 'sudo trimforce enable' command on all my systems, using various SSD brands ranging from Samsung EVO to Seagate, no issues. Graphics much faster, especially noticeable in a VM, where before bringing up Grid view from the Dock, you could literally see the screen redraw.
No drops at all in the 24 hours since installing. The return of mDNSresponder (ba bye DiscoverD!) has fixed all my network share and connection problems. 10.10.4 is the first version of Yosemite that now feels on par with 10.9.5, in terms of responsiveness, stability and speed.
