i det seneste år har det ikke været muligt for MacOSbrugere at trimme deres ssdiske. Vel og mærke kun hvis de bruger ikke originale diske. Apple understøtter selvfølgelig trim funktion  på  deres egne diske.

Er det så  noget der kommer mig ved spørger Du?  Ja det er det hvis du selv har sat en ssdisk i din maskine maskine. Det er der mange der har. Læs dette og undgå at din  maskine pludselig crasher.  Min gjorde men jeg havde fuldstændig styr på backup. Det blev kun en kort afbrydelse.

Her kommer et klip fra Mac roumers.

Earlier today Apple released OS X 10.10.4, an under-the-hood update to OS X that introduced several bug fixes and improvements. One improvement, according to Ars Technica, is support for TRIM for third-party SSD hard drives. We previously covered TRIM likely coming natively to the next version of OS X El Capitan but it appears support has already arrived.

With today’s OS X 10.10.4 update, however, Apple has added a command line utility that can be used to enable TRIM on third-party SSDs without having to download and install anything. Called trimforce, the utility can be executed from the OS X terminal, and it requires a reboot to start working.
TRIM is a system-level command that allows the operating system and the drive to communicate about which areas of the drive are considered unused and thus ready to be erased and rewritten to. In the absence of TRIM, users can see significantly slower drive writes as the drive begins to fill up. Most modern operating systems support TRIM but for Apple’s OS X, it has only included support for its OEM SSDs. This means that Mac users looking to install an after-market SSD in a machine originally intended for spinning disc hard drives would run into trouble without the help of other third-party tools.

To enable TRIM, a user just has to type “sudo trimforce enable” into the Terminal window. Ars Technica points out that running TRIM prompts a “scary” message from the system, but notes it’s largely because each SSD implements TRIM in a different way, with older disks sometimes acting in a way OS X would not expect.
