How to increase system disk space in Mac OS X Yosemite?

Question

macOS

Are there any True Macdrochers here? I really need your help with advice. Before that, I had Mavericks 10.8.4 on the SSD, and when Yosemite 10.10 came out, I split the SSD into two partitions and rolled a new axis onto the smaller 33 gig partition. At first it was completely raw, and after several updates it became more and more stable to work, and thus I gradually migrated to it. And so I decided today to completely transfer to her. I deleted the 86 gig partition with the old axis and now I can’t stupidly expand the partition with Yosemite. And there are 86 gigs of free space on the hard drive. Where to dig? Google is silent, or shoves links to some junk. And I really need a place on the hard, Photoshop sends me to hell because there is no free space, all the work has stopped

Answer 1

We create a new 86-gig partition, transfer everything from the current one in the Restore tab in Disk Utility to it, boot from it, and after that it will be possible to expand the large partition.
You can expand only the partition located "at the beginning", and you have a smaller one (33-gigabyte), apparently, turned out to be "at the end".

Answer 2

I solved the issue differently. I created a small partition on the HDD, transferred the system there, booted from it, erased the SSD and then transferred the operating system to a clean SSD, and then erased the partition on the HDD. But I'll keep that in mind, thanks for the advice.
