To install Catalina on another Mac, first make sure it's powered off, then simply plug in the USB installer you created and turn the Mac on. When you hear the boot tone, hold down the Option. Install MongoDB. Brew install mongodb-community or brew install mongodb. Before you can use MongoDB, you need to create a /data/db folder because MongoDB expects this directory (/data/db) on your machine to save the data. But Apple has already depreciated this directory on Catalina/BigSur machines and created a new volume on macOS Catalina. Mac OS Catalina 10.15.4 I installed the MongoDB server Community edition on my Mac without a problem (seemingly). I then installed MongoDB Compass community edition, from the MongoDB download. Navicat for MongoDB gives you a highly effective GUI interface for MongoDB database management, administration and development. If you have already done this for a previous installation of MongoDB, you can skip this step. To install MongoDB, run the following command in your macOS Terminal application: brew install mongodb-community@4.4. Created with Sketch. Alternatively, you can specify a previous version of MongoDB if desired.

Question or issue on macOS:

Mongodb Install Mac Catalina Os

I recently installed mongodb-2.6.0 with Homebrew.
After successfully installed, I tried to connect using the mongo command. I am receiving the following errors which do not allow me to connect:

How to solve this problem?

Solution no. 1:

It can happen when the mongodb service is not running on the mac. To start it, I tried

and it worked.

Edit: According to the discussion on this PR on homebrew: https://github.com/Homebrew/homebrew/issues/30628

brew services is deprecated, I looked around on SO and found these answers now answer the question: What is the correct way to start a mongod service on linux / OS X?

Solution no. 2:

I encountered the exact same issue and here is a clear step by step process to avoid this error.

Step 1 – Installation ( Don’t follow this step if you have already installed MongoDB ):

Step 2 – Run Mongo Daemon:

Step 3 – Run Mongo Shell Interface:

In this sequence, I was able to run the mongo command without any error. I have also detailed the error trace and its solution on this blog.

Solution no. 3:

To solve your issue you need to follow the instructions which are then given to you by brew after you use “brew install mongodb”.

To have launchd start mongodb at login:

Then to load mongodb now:

Or, if you don’t want/need launchctl, you can just run:

You may be able to just run that last command, but it didn’t work for me and I needed to run the second command. To save me in the future. I just ran the first command too. Hope that helps!

EDIT Hrishi’s method of using brew services mongodb start worked good for me. I think they should include this in the mongo docs.

Solution no. 4:

In another tab, you can start the mongo shell with

mongod

Wmv player for mac. Then return to the previous tab and try again. If you’re having trouble setting up your mongoshell, check out this link on the mongo shell: http://docs.mongodb.org/manual/tutorial/manage-mongodb-processes/
or this link on installing mongodb:
http://docs.mongodb.org/manual/tutorial/install-mongodb-on-os-x/

Solution no. 5:

I was having the same issue when calling mongod from the command line.

I resolved this by calling instead sudo mongod.

Solution no. 6:

I had the same error but a different root cause. Thought I’d post the solution here in case anyone else runs into the problem. I got this error after my Mac improperly shut down while I was running mongorestore -d foo dump/foo/.

tl;dr: I fixed the problem by removing the damaged foo.ns file along with foo.0, foo.1,… from my data folder /usr/local/var/mongodb/. Then I restarted the mongo server with brew services restart mongodb and I was back to normal.

Details: I kept getting the error even after trying to start or restart the mongodb service via brew or launchctl. Eventually I ran
mongod --dbpath /usr/local/var/mongodb
and saw that the service was not actually starting, and the start sequence included the following error:
[initandlisten] bad .ns file: /usr/local/var/mongodb/foo.ns [initandlisten] User Assertion: 10079:bad .ns file length, cannot open database
I got rid of the bad .ns file and the rest of the data files, and the next time I started the service I was good to go.

Solution no. 7:

for me on osx, I had to kill old running instance, then restarting worked.

Solution no. 8:

For anyone who is here looking for the answer for this after your mac has updated to OS Catalina

Solution no. 9:

I got this error after I upgraded to mongo 3.6 with homebrew.

The log /usr/local/var/log/mongodb/mongo.log contained the message shutting down with code:62. This error code means that the existing database is too old to run with the current version of mongo.

I found 2 solutions in another SO question:

Delete your database folder (/usr/local/var/mongodb)
Or follow the upgrade procedure

I chose to upgrade. In my case, that meant I had to downgrade to 3.4, run a command in the mongo console, then upgrade again. Mongo requires you to upgrade one major version at a time, so depending on how far back you were, there could be additional steps. The docs will guide you.

Install Mongodb Mac Catalina

The brew switch * and brew services restart commands made swapping between versions relatively painless.

Solution no. 10:

If you have already installed MongoDB then first try to run mongod as a sudo user, I was facing the issue because of not running mongod as a superuser.

I have pasted the o/p for both the commands(mongod and sudo mongod) at very bottom, you can check that too but

First try this

not this

I had installed MongoDB on my MAC OS X Sierra 10.12.6 by by running the following command in sequence.

then created a directory to which mongod process will write the data, this is optional as mongod process takes it by default, see this useful guide at https://docs.mongodb.com/manual/tutorial/install-mongodb-on-os-x/

Finally started mongod process as follows

Oputput of mongod (failed) and sudo mongod (succeeded) commands on my terminal.

Then I opened new terminal to start querying the MongoDB, it worked.

That’s it.
