Recovery HD

[Tech198]

I'm assuming after you boot to Recovery (Command+R), on power on, the image is loaded *fully* into memory, as the oonly way i can see the following were possible:

- I booted to Recovery
- Then, went to Disk Utility and wiped entire SSD, no just volume:

* SSD
* Container (AFP)
* ....the rest


I selected SSD (top most) and erased this completely, so it was the only thing listed.

After this, i created new partition and processed with install just fine

I believed if i rebooted after deleting but before installing, then i would have got the "?" not possible. But the image was n memory as the only reason i could install locally

However its was so dam, slow... compared other times where booted via ther methods (Internet recovery, usb etc)



I can't explain that... but it did install *finally*. Even being on SSD on MBA, install time this way must of taken about 30 minutes just the first half (...it felt like 30 minutes, but it could of been longer.)

I always thought it downloaded from apple servers?

Usually it is, based on this install time, but I can conform its local recovery in this sense.,,.. Just wondering why it took much longer than it should have if its was only Command+R...

I guess a good alternative workaround, but since I erased the entire SSD, got something to do with lengthily install even despite it was not rebooted at all between

Did Apple update something i wonder..From memory this was never possible, so was surprised why it even worked at all.

I completely erased my Mac using recovery yesterday MBA M1. I then reinstalled OSX took about an hour.
