Currently, Joost runs on the latest Macintosh computers equipped with Intel processors. Recommended minimum specifications are as follows:

* Any Intel-based Mac running OS X 10.4
* 512 MB or more RAM
* About 500 MB free disk space
* The Joost software is a 15 MB download, expanding to 35-40 MB on disk. The remainder is used as a cache

* Broadband/ADSL (1 Mbit/s downstream, 512 Kbit/s upstream recommended, although lower speeds may well work)
* In 1 hour of viewing, 320 MB will be downloaded and 105 MB uploaded, which means that a 1 GB cap will be exhausted in about 10 hours (see important note below
