USB ZTE Modem will crash your Snow Leopard. Here is how to fix it.
Today, we have a customer who have installed the ZTE Modem 626 on her brand new Macbook.
The thing is, when she installed it, everything went smooth and no problem found. But, after you reboot it, you’ll find the spinning gear forever.
This is due to, a poor driver collecion by ZTE, which replaces the original /usr/lib/libcurl.4.dylib with it’s version which has no 64 bit version in it.
So, if you want to install the ZTE,
1. first backup the /usr/lib/libcurl.4.dylib file,
2. do the ZTE installation
3. before you restart, replace the /usr/lib/libcurl.4.dylib with your backup.
If you have installed it, and you can’t boot the Snow Leopard, here is what to do,
1. Download libcurl.4.dylib here
2. Boot in target mode (holding T key while booting) while it is being attached to another mac using a firewire
3. replace the /usr/lib/libcurl.4.dylib with the one you have just download it
4. reboot the system. You should be able to boot and use your modem.
Dear Sir/madam,
i am so happy to get a reply for the problem of ZTE modem. I am new to mac and installed ZTE usb modem. Belive me for the last 10 days my head was rolling and could not find any solution to fix rather formating. I don’t want to reinstall since i had lot of data in my mac. I found your answer and now, YES>>>>Its working., Thanks a lot to you…..
Hello
Thanks a lot for this very usefull post… I plugged in a ZTE modem on my Macbook this morning, then restarted it because it created some unstability, then got stuck with the spinning gear… I don’t know what I would have done if I had not found your explanations… probably take it back to Apple store where I’m not sure the diagnosis would have been correct !
Just to mention that mounting a memory key with the correct libcurl.4.dylib file under single user mode and perform the copy can be an alternative to the Target mode you suggested if, like me, you don’t have another mac available..
Anyway… Thanks again for posting this !
i download the file to a flash usb,and restore it to mac with simple user mode. it works , thanks a lot.
