Quindi niente di più semplice!esco ha scritto:Su due macchine con SSD uso bene Trim Enabler e Chamelon di Alessandro Boschini (non noto differenze)pier88tp ha scritto:scusate la domanda mi potete dire come attivare i trim con Trim enabler 3.3?
i passi che si devono fare? ho un mbp 2011 con samsung 850pro 512GB.
da premettere che uso il mbps con i trim disabilitati.
serve solo installare trim anbler e attivare? o prima si deve disabilitare il kext?
grazie per l'aiuto
Ecco la procedura richiesta (vale sono per Yosemite):
- scaricare l'ultima versione del software (Trim Enabler o Chamelon)
- installare il software (entrambi automaticamente disabilitano Kext Signing)
- riavviare il mac con Yosemite
- lanciare il software ed attivare il trim
Da questo momento il computer con Yosemite sarà privo del Kext Signing.
La necessità di questi software di disabilitare il Kext Signing è spiegata qui sotto (era una nota di Trim Enabler prima del suo aggiornamento).
TRIM ENABLER
As some users may have noticed, if you try to enable Trim on OS X Yosemite, you can get stuck with a grey screen with a stop sign during boot. And as detailed in these two posts., this issue was due to a new feature in OS X Yosemite. In OS X 10.10 (Yosemite), Apple has introduced a new security requirement called kext signing. (A kext is a kernel extension, or a driver, in Mac OS X). Kext signing basically works by checking if all the drivers in the system are unaltered by a third party, or approved by Apple. If they have been modified, Yosemite will no longer load the driver. This is a step by Apple to lock out anyone from making software that interacts with the system, to make the Mac experience more and more similar to iOS. Since Trim Enabler works by unlocking the Trim driver for 3rd party SSD’s, kext signing prevents Trim Enabler to enable Trim on Yosemite, at least out of the box. Currently, there is only one way to continue to use Trim Enabler and continue to get Trim for your third party SSD, and that is to disable the kext signing requirement. While it is unfortunate to have to disable kext signing, it still leaves you with the same amount of security as in OS X Mavericks, where the kext signing requirement didn’t exist.
Installo Yosemite sull'ssd, poi scarico trim enabler e lo installo
Riavvio e abilito i trim
Grazie
