Toshiba Satellite C875-S7304 update to Big Sur

Hello All, i have been running Catalina for a while now on my Toshiba.  I was wanting to upgrade to Big Sur.  Just wondering if this is an easy upgrade? I do have the hd4000 graphics, will that be a problem? (Using Clover at the moment).

Any help would be appreciated.

thanks!

Big Sur still supports HD4000 graphics OOB and is the last version to do so natively; however, it did drop support for Ivy Bridge MBP9,x/10,x so you'll have to use the SMBIOS of, say, a Haswell MBP11,x or Broadwell MBP12,x model for installation; you'll only be able to boot Big Sur with an MBP9,x/10,x SMBIOS with the -no_compat_check boot arg but you'll receive no macOs update due to unsupported SMBIOS/Mac model.

 

With Clover, I recommend you update to version r5133 or higher. You'll then have to boot the Preboot partition.

 

Do post your system's specs, ideally in signature.

Thanks for the reply Herve, i added specs to my sig.  So I changed to MBP 12,1 and now it is wanting me to upgrade to Monteray.  Is there anyway to upgrade to Big Sur?

I also have an older version of OC that works with this laptop, but i tried updating to the newest version and i get an error ocb load image failed, unsupported.  Should i just stick with Clover or try and get OC working?

Thanks again for the help, its been a while, just getting back up to speed.

We also have download links for Big Sur installation package in Our Picks forum front page section. Or you may opt for a Haswell MBP11,x SMBIOS given that those were dropped in Monterey. Software Update should only offer you Big Sur with such an SMBIOS.

I used the compare tool for OC config.  Anything obvious i need with the new version of OC?
