Buongiorno, ho da poco messo a posto quasi tutto sulla mia prima configurazione hackintosh che va benissimo. In questi giorni è apparso l'aggiornamento di sicurezza di High Sierra come da titolo e me lo ha scaricato ma prima di partire con l'installazione vorrei avere delle delucidazioni riguardo agli aggiornamenti in generale soprattutto ai minor, per ora non ho bisogno di aggiornare a Mojave.
Si corrono dei rischi ad eseguire aggiornamenti di questo tipo (sicurezza come in questo caso) o ad esempio a versioni piu nuove dello stesso sistema MacOS? Se sì quali sono e come si prevengono?
Non vorrei ritrovarmi a dover re installare tutto formattando il disco partendo da zero. Qualche tempo fa ad mio amico succedeva che il disco veniva crittografato con "Filevault" e diventava inaccessibile, questo dopo un minor update, al che ha dovuto ricominciare da 0. Cos'è il Filevault? Potrebbe capitare questo anche a me? Vorrei sapere tutto prima di andare a fare delle minchiate.
Grazie in anticipo a chi vorrà e avrà la pazienza aiutarmi.
Ciao a tutti ho visto che ci sta un aggiornamento, il 10.14.1 e vorrei un consiglio, posso fare l'aggiornamento tranquillamente o creo un casino?
Ciao e grazie
Hello. My hardware is: AMD Athlon X2 7750 dual-core Gigabyte NVIDIA 8400GS 512MB ( [VGA] ,HDMI,DVI) Motherboard Gigabyte based on NFORCE without AHCI support (only IDE) I have successfully installed Mac OS Yosemite, Mavericks and El Capitan with AppleNFORCEATA.kext But I can't use it with Mac OS 10.8, don't know why, it just gives error and my internal HDD's are not appearing in Disk Utility.
I have a Mac Mini 2006 (upgraded) with Intel GMA950 graphics, running MLPostFactor 10.8.5. It is connected to an ASUS VS197 LCD panel using DVI-D. This is natively a 1366x768 panel that is recognized and works fine.
However, the other choices for resolution are 4:3 800x600 and 1024x768, and then the oddballs 832x624 and 1360x768. None of these are useful as a low-resolution widescreen for gaming or watching DVD content. Specifically I want to get access to 848x480 or 854x480, and also 1024x576. SwitchResX makes these choices available, but it doesn't work with a "full screen" game, presumably because the game directly queries OSX Display to get a list of valid resolutions and SwitchResX is bypassing that system instead.
So the solution is obvious: buy a new computer pull the monitor's EDID data, hack it to enable new resolutions, and then tell OSX to use this custom EDID instead of the one retrieved from the monitor.
Following the steps of the EDID injection guide, here is where I am:
* Retrieve EDID, DisplayVendorID etc from ioreg.

* Use an EDID editor to enable new 848x477 and 1024x576 resolutions. (Verify with an online EDID tool, and compare to the previous version)

* Create a new subfolder and plist within /System/Library/Overrides/Display/ containing the new EDID string and monitor name.
* Reboot.
Now the problems begin. Even though the plist file is being read (which I know because the Monitor Name has changed in Displays), the custom EDID is not being used. When I dig into IORegExplorer I am able to come up with AAPL00,EDID string and it is the unmodified one read from the monitor. I even tried a plug-and-unplug while OSX is running, and also tried to reset the SMC and NVRAM, but no dice.
Do I need to start digging into DSDT hacking? Is the Intel driver pulling down EDID during boot and I need to override it somewhere else? What am I missing here?
