Guide To Install Yosemite on HP Laptops with Clover UEFI

[Craigrox]

I just tested on my 4540s. First I checked 'pmset -g assertions' to be certain they were all clear. Then I closed the lid. It went to sleep. In fact, I think the delay for sleep is shorter than it was for Mavericks.

I'll use this in future to check for any assertions that could keep it alive, of course when I just tried closing the lid it worked fine.. Also noted the delay is shorter than previous OS versions.

Be aware that (left)ctrl+prtsc or (left)ctrl+fn+delete are keyboard shortcuts for toggling that mode.

Definitely useful to be aware of these! I never realised. Though I swear I never touched them but you never know lol.

Thank you for taking the time to test this on your devices and being so informative as always

Tried to Instal using 2b Manual method. I get to the install screen after partitioning my SSD drive. After I select the SSD to install on, it gives me an error. Any ideas why, and how to fix please.
Thanks

You must have made a mistake in creating the USB. Read/follow the instructions carefully. It is tricky if you haven't done it before.

Question: I used the sticky from Rehabman "Guide to Installing Mavericks on HP Probook" to install Mavericks on my 4730s with 1080p screen. I actually have 3 partitions, one Win 8.1 Pro and two Maverick partitions running on a 500GB SSD. Its been extremely stable and has worked very well.

How would you recommend I move to Yosemite... should I follow this guide using Clover UEFI, and would I be able to move my 2 Maverick partitions one at a time, i.e. run Yosemite on one partition for a few weeks before upgrading the other? I would also not like to remove my Win 8.1 Pro partition since its running Quicken and has all my finances on it (Quicken its the only reason I still run Windows).

It might be a dumb question since my Mavericks installation is not installed using Clover UEFI.

Thanks... time to donate again.

Of course, you have to migrate to Clover first. That is post #1, here: http://www.tonymacx86.com/hp-probook-mavericks/112383-guide-install-mavericks-clover-bootloader.html

After you do that...

just wanted to say thanks. I reinstalled from scratch after doing a backup, went through this guide and it worked perfectly.
Had a slight moment with the F4 key, I pressed it and it locked the keyboard for quite a while, I left it and then perssed enter, and away it went.
Now I have a laptop that sleeps perfectly, usb works, my hd screen works, I moved to Clover (so updates should be easier).
Thanks for all the effort put into this, much appreciated.

No idea without a photo. We are not telepathic, but I'm 100% certain you're not actually seeing the text 'blahblabla'...

It takes a while for Clover to write the ACPI files to the USB. USB flash drives are slow.

Hey,

I had Mavericks installed on my 8460p - and then wanted to do a clean update to Yosemite. I created the USB-Stick, formated the HDD and installed Yosemite successful.

Now, when i try to boot osx, it tells me, that my system is locked and i have to enter a 6 digit code.

i tried to reinstall several times. installed windows to clean ram etc. and tried again to install yosemite.
i also tried to HardReset my HP (take battery/ac out - press PowerButton for 15s) but no luck.

i always end up with that locked-page :/ what can i do?
