Hello community! I have a 2010 MacBook Pro for which I had to replace the hard drive. I formatted the new hard drive to Mac OS Extended (Journaled) and installed it in place of the old one. In addition, I started the process of "Creating a bootable installer for macOS" found here and on Apple's online support through my 2009 MacBook that is already running El Capitan (I went to the App Store, my purchases ...). Booting with the alt key on the MacBook Pro! I select the bootable installer. The Apple logo appears! The progress bar too. After 5 minutes ... a fleeting black screen then a white screen ... and nothing more! I also tried the command r keys: a world map appears, I select the network (by the time I figured out that my keyboard had switched to QWERTY and that I shouldn't press SHIFT for the numbers, several days had passed!), of course I also tried safe mode, or without wifi with ethernet. Nothing! Always the white screen, it's been a week that I've been going around in circles, going from tutorials to forums! Thanks to whoever can help me. Additional question: this MacBook Pro originally came with 2 sticks of 2GB memory, can I upgrade this memory ... once it comes back to life?

Hello, Since your 2009 Macbook is already running El Capitan, you should be able to download El Capitan here: http://updates-http.cdn-apple.com/2019/cert/061-41424-20191024-218af9ec-cf50-4516-9011-228c78eda3d2/InstallMacOSX.dmg Then, still using this operational Macbook, create a USB installation drive using this method: https://www.commentcamarche.net/faq/44770-creer-une-cle-usb-d-installation-os-x-10-11-alias-el-capitan Next, start the 2010 Macbook pro with the USB drive inserted while holding down the alt key so that the Mac prompts you to choose the startup disk, then select the USB drive, go through Disk Utility before installation, to format the disk as Mac OS Extended (Journaled) on GUID Partition Scheme, and finally install El Capitan. Best regards.

Have you attempted a hardware test again? (once the Mac is connected via cable to the router)
