moonman Posted November 23, 2016 Share Posted November 23, 2016 Serious problem here. Trying to create El Capitan USB installer for Dell e6230, following Herve's guide with Enoch. Though the first part is the same as Jake Lo's guide with Clover. It's now 4 different times that I had this problem, working on my 2009 Macbook Pro with El Capitan, where the desktop goes black and then the computer freezes, and I have to force restart. - first time, mounting BaseSystem.dmg - the other 3 times, when copying Packages to the USB drive I've redownloaded the El Capitan install app, in case it had been corrupted. I've tried different USB drives. I've never had this problem with other times to create a USB installer, but if I remember maybe that was creating installers for Yosemite and Mavericks. I have created El Capitan installers, but I don't remember if it was on this Mac, a 2009 Macbook Pro running El Capitan. P.S. in my sig I have an e6230 with El Capitan, so obviously I succeeded before to install it. I don't have that USB pen anymore though. Strange. Unless I created that first USB on a different Mac.

Administrators Hervé Posted November 24, 2016 Administrators Share Posted November 24, 2016 Why don't you try to create your new USB installer directly on the E6230? It makes no difference that it already runs EC. Link to comment Share on other sites More sharing options...
Administrators Bronxteck Posted November 24, 2016 Administrators Share Posted November 24, 2016 hmm I think 2009 mbp had gpu issues one of the symptoms was going black or just rebooting sometimes it was a grey screen with stripes. hopefully thats not your case.

moonman Posted November 25, 2016 Author Share Posted November 25, 2016 Yes, it's weird. Have to say that the MBPro works perfectly though. The only problems I've had are when trying to create the USB pen. Link to comment Share on other sites More sharing options...
