He still won't give me Jacob's Password to the executive terminal inside Med-tek Reaserch. This is because I already have a Jacob's Password key item of the same name from Covenant.

This is the last companion perk I need to unlock and it's driving me crazy. I'm playing on Xbox One by the way.

I thought that password was on the desk at Med-tek ?

I've done that combination of quests 3 times and it has never caused me an issue...

No. MacCready is supposed to give you the password as you both approach the terminal. I tried this on a new character.

The 1.3 patch probably only fixes a bugged quest if you either haven't gotten the quest yet or have gotten the quest but have not gotten to the point in the quest where the quest becomes / can become bugged. Your only likely option is to load an earlier save file, if you have one, from before you entered Med-tek Research. However, I am not sure exactly how much of an impact having the Covenant Jacob's password already in your inventory would have. I managed to finish the first part of MacCready's companion quest, which can possibly become bugged, without issue with the 1.2 patch. I haven't yet gotten the 1.3 patch.

So I somehow managed to glitch through the roof and some of the walls using my power armor's jetpack. I fell into the room with the elevator and it let me ride it to the bottom where the cure is. I picked up the cure but it doesn't trigger anything. MacCready still doesn't acknowledge that I picked it up. I also went to Daisy in Goodneighbor too and she doesn't say anything about the cure either. My quest log is still stuck on "Locate the Executive Terminal".

Darn, I thought I almost found a solution.

Usually bug fixes like this only work if you haven't yet encountered the situation. If you're hovering at that point in the quest currently, it can't prevent the bug from occurring since it's already occurred.

So, I started a new game over and deliberately avoided doing MacReady's personal quest because of the combat breaking bug in his perk.

Now I find out that because I didn't do his quest (but did do Covenant) that it is no longer possible to do so.

I already hated MacReady because he brings the horrible Little Lamplighters disaster back into the game. I didn't need more reasons!

You and me both. Luckily, you can still get the magazine inside the med-tek building. You can use the jetpack and glitch though the open ceiling in the terminal room.

So is MacReady's perk still buggy (i.e. 2000% better head shot chance instead of 20% better) or has that been fixed?

ahhh, just read the whole list, it says Macreadys perk has been patched. I'm excited to try it. Just need to figure out where I stashed him, get him as my companion, and then steal some stuff. That should trigger it
