Nikon D90 Installation Disc?

I have lost my installation disc for my Nikon D90. I can't upload pictures onto my Mac without it and was wondering if there's anywhere online I can download the software for free? I've tried looking around but have had no luck.

Most of us regulars here recommend and use usb card readers for upload. They're not expensive and are available where ever cameras are sold.

You do NOT need an installation disc!

Just use the card reader on your Mac and the file manager Finder to copy all the images from your memory card to your computer. Remember to make a new file folder that will remind you what subject and date you shot.

I hope you read the user manual and formatted your memory cards using the format feature in your cameras menu, page 202 in the manual
