Common
Hiccups.
The stuff that trips up almost every new Claude user, and how to fix all of it before it becomes a real problem.
None of this is your fault.
When something breaks or acts weird, the first reaction is usually “I did something wrong.” Nine times out of ten, you didn’t. You just ran into one of the same five or six things that everybody runs into. So let’s go through them. One at a time. Nice and easy.
The “not enough disk space”
problem.
If you are using the Claude desktop app, it runs inside something called a virtual machine. Think of it like a tiny computer inside your computer. And that tiny computer only gets a small amount of storage space to work with.
Signs that your disk is full.
• You see an error message mentioning “disk space” or “no space left on device”
• Things that used to work suddenly stop working
• The app gets slow, laggy, or freezes during file operations
• Downloads or exports fail without a clear reason
Clearing space on your Mac.
du -sh ~/Library/Caches to see how much space your app caches are using. You can safely delete most of those.Use VS Code instead
of the desktop VM.
This also means your files are real files you can see in Finder, back up to iCloud, and organize however you want. It is a straight upgrade for anyone doing real work.
Your stuff is out of date.
This is one of those things that feels too simple to be the problem, and that is exactly why people miss it. Claude gets updates. VS Code gets updates. Extensions get updates. And when any of them fall behind, things start acting weird in ways that are hard to diagnose.
Three things to keep current.
Someone else changed
their system.
• An API might change its URL structure or authentication
• A service might deprecate a feature you relied on
• A platform might change its rate limits or data format
This is normal. Check the service’s status page or changelog when something breaks that you did not touch.
Claude starts forgetting
what you said.
You have been going back and forth with Claude for a while. The conversation is really rolling. Then Claude starts repeating itself, forgetting instructions you gave it earlier, or producing answers that feel way less sharp. What happened?
Think of it like a whiteboard.
When the conversation gets long enough, the earliest parts start falling off. Claude is not ignoring you. It literally cannot see those messages anymore. It is working with whatever is still on the board.
Start fresh. On purpose.
Claude keeps asking
for permission.
You tell Claude to do something. Instead of just doing it, a popup appears asking you to approve the action. Then another one. And another one. It feels like Claude does not trust you, or you do not trust Claude, or something is broken. Nothing is broken.
It is a safety feature.
What triggers the prompts:
• Creating, editing, or deleting files
• Running commands in the terminal
• Installing packages
• Anything that touches your system beyond just reading
This is actually a good thing. It means Claude will not accidentally delete your files or run a command you did not want.
Adjust it to your comfort level.
“I know it is installed,
but Claude can’t find it.”
You installed Node, Python, Homebrew, or some other tool on your Mac. You can use it in your regular terminal just fine. But when Claude tries to use it, it says “command not found.” This is probably the most confusing error for new users because it feels like Claude is just wrong.
Two different maps
of your computer.
node or python, your computer checks that list to find the right program.The issue is that Claude’s terminal session might load a different version of that list than the one your regular terminal uses. Different map, different results. A tool can exist on your machine and still be invisible to Claude.
Give Claude the right map.
node, you can ask Claude to use the full location like /usr/local/bin/node. You can find this in your regular terminal by typing which node (or whatever tool).nvm or pyenv to manage tool versions, those tools modify your PATH through config files. Claude can help you make sure those config files are set up correctly.When something goes wrong,
run through this list.
You are the
operator.
Running AI is like running any system. Things need maintenance. Apps need updates. Storage needs managing. That is not a sign that something is wrong. That is a sign that you are actually using the thing for real work.
