How to Clean Install macOS / OS X Without a USB Drive

OS X Mavericks is quite good, and is at least optimized for most hardware. What goes in box with WiFi or antenna next to it? And what goes in box with lock? What do I click on check or enter.. Do I have to put in a disk to reinstall mountain lion or should something come up that I can choose from? I have followed these instructions and successfully get to the point where I can reinstall Lion. This process has repeated itself several times. Any ideas what to do from here? Thank you.

Installing Lion on Core Duo

I followed the steps in this article and sure enough I got to the point where I had the option to reinstall and the OS offered was Mavericks the one which came with the MacBook Pro. This is what I wanted: Downgrade from Yosemite to Mavericks. However, since I have a second partition for my file storage separate from the system partition I clicked on that and it is now installing.

Once if it installed can I just erase the partition where I have Yosemite and get rid of it altogether so I just use Mavericks or it would be better to keep both and dual boot? Instead of re-formatting if that is the right terminology my macAir, I accidentally selected my external time machine hard drive ouch. How do I proceed?

And afterwards delete the 1st partition? At present that is one of the few things I can click on. Disk 1 cannot be deleted because it is d place where os x utilities is installed Do nothing on this and just close the window. Now click on reinstall mac or install mac os x. Let it go.

Hi, I recently bought a Mac Book Air as My Mac Book Pro failed on me and when you turned it on it went to a file on a grey screen flashing with a question mark on it? I have got macbook pro early model.

Later on I upgraded it to Mavericks. Recently I thought of upgrading it to Yosemite which I did. On successful installation I realised that It is extremely slow and found out that it is encrypting my whole hard disk. I left it for hours and hours but it looked like it stuck on that process. And also did not allow me to stop the process. I turned off my macbook using power button kind of hard stop thing. When I tried to turn it on, it stuck on safe mode and nothing was happening.

I could not log back in and I tried all the diifferent methods like PRAM reset, safe mode, disk utility tool to repair the disk but nothing seemed to work. Luckily I had backup in Time machine from last year which restored my system back to Mavericks. I started using it and it was working fine. Yesterday while closing my system I used Power button and did that forced shut down kind of thing again and since then it is not turning back on properly. From safe mode I tried to restart the system but since then it stuck on Grey Barred Circle thing.

I decided to use Internet recovery method when all other methods failed including safe mode, pram reset, single user command. Please help me. Any reason why this is happening? Or has it not taken my password? I see no horizontal progress bar, only spinning gear there.

How to reinstall macOS, even without Recovery Mode -

This is not a walkthrough on downgrading mac, this is a walkthrough on using Internet Recovery to reinstall OS X that came with the computer. Would this style work in this case?

One day at work I found a Macbook Air in a recycling box. My boss let me keep it, if I made sure I wiped it clean. So I arrogantly booted it up, showed it to him, and did internet recovery. I have used recovery partition several times, and it is relatively slow on WiFi , but infinitely useful way to fix serious performance issues.

Therefore, once the operation is complete, you pick up where you left off, all apps and settings and docs are right where you left them and no Restore from backup is needed. I agree! Hi Jack, Ive been having this issue where first of all if I just boot the imac, it just keeps restarting over and over. This seems to happen no matter what startup commands I try.

I dont care if everything on the computer gets deleted I just want to get this thing working again. Downgrading with Internet Recovery is not a good idea at all.

Mine has taken so long to get through the internet recover mode to reach the OS utilities and I think it will take longer to download the OS from the internet. I would like to know how I can install from the OS setup that i have copied to my usb drive. Name required. Mail will not be published required. All Rights Reserved.
