Not sure if you're still using the 2013 MBP? I happen to use the same model with Lightroom and photoshop.. A workaround that works for me is is using a SanDisk Portable SSD 500gb ext ssd for caching and all adobe storage.. I leave the mbp pretty much empty.. I just can't have too many files or apps open at the same time.. especially illustrator. I use 4-5 adobe apps, I plan and juggle the open apps.. I still only have 8GB of ram in 2024. I am going to build a proper rig very soon tho.. This 2013 has gotten me this far.. The HDMI is replaceable just do a fresh install of OS afterwards if it doesn't recognize it at first.
