Do you have a data plan or WiFi? If you do you don't need a specific app to use your hero on your mac since most of it can be done wirelessly.
File transfers can be done like any mounted USB devices.

The only things that will require windows is the firmware upgrade stuff AFAIK. I have a mac and I have not required it to connect with my computer except to transfer files.

 

To copy files to / from the device, just connect it via USB, mount the sd card from the phone, and then the drive appears as a disk on the Mac (as any USB stick would).

 

Hi!
Actually, being a long time user of Mac (since more than 15 years now), I searched around and found this software yesterday:

Keep your life in sync with The Missing Sync for Android from Mark/Space

Haven't had a chance to install it in my Macbook Pro yet, but I'm planning on doing it this evening.

Good luck!

 

Been using the Beta for Missing Sync for a few days, it's definitely a must if you want to Sync up with your iCal and addressbook.

 

I've had missing sync for both my Palm and WM phone in the past, and I think they're great products.

That being said, I don't think it's useful for majority of android users. If you have a data plan or even WiFi, you can sync your phone directly with google accounts.

You can also have your iCal and Address book sync with your google account too, so everything will be updated.
