the forbidden symbol.Ĥ- I read that it could be the flex cable of the hard disk, so I bought one, but before replacing it I decided to put the hdd back in its place to see if it was the cable or something else. I researched on the forums what that symbol meant.Ģ- Formatting in Macos Plus (with registry) and installing the OS that comes by default on the computer (LION), and from there start updating to High Sierra, I knew that the process would be very slow, but I wanted to eliminate all the possible options.Īll good, but again after a few reboots the forbidden symbol appears again.ģ- I read in a forum that having changed the Ram could be the reason why it gave me a failure, well, I put the two original cards that came with the mac back in, but without any success, it appeared again. Everything installed without a problem, but after a few hours I turned the computer back on and a forbidden symbol appeared. The steps that I followed were the following:ġ- I removed the hdd and put the ssd in its place, enter system recovery (cmd + r), format the disk in APFS and installed the OS from the internet. The fact is that I decided to remove the cd and replace it with a ssd, so use this for the OS and leave the hdd for storage. I have a late 2011 Macbook Pro with High Sierra, I expanded the ram and now it was time to put an Ssd to make it go faster. Let's see if you can give me a hand, because I've been crazy for two weeks and I don't know what else to do.
We press Command + R with which we will be able to reinstall the most recent version of macOS that had been installed on our Mac (recommended by Apple itself in many cases) then we have the possibility to press Option + cmd + R with which we are going to update to the most recent version of macOS that is compatible with our Mac and finally the longest combination that would be Shift + Option + cmd + R with which we will reinstall the macOS that came with the Mac on a startup or the next available version.Īny of these options serve us in these cases, we hope you do not have to use them but if necessary here you have it.
We can use the key command option when starting the computer. In all Mac models, the boot is completed when the Finder menu bar, the desktop and the Dock appear, so in this case what we have to try is to install the system again and for this we have to follow the same Previous steps. The solution in this case is very simple and we only have to reinstall the operating system on the Mac to get out of this failure. Question mark in a folder when my Mac starts up How can we solve this problem on our Mac
