Jobs, whoto remove cancer from his pancreas, is attending some company meetings and plans to return to full-time work later this month, Apple spokeswoman Katie Cotton said.
The rare cancer was a far more curable form than typical pancreatic cancer, Jobs wrote in an e-mail to employees after his surgery.
At the time of his surgery, Jobs, 49, had estimated he would return to work in September. That apparently is on track.
Tim Cook, an executive vice president who oversees Apple's sales, operations and Macintosh unit, has been running the company's daily operations during Jobs' absence.
In the past month, the company has had its ups and downs. Last month, it unveiled its new, but also that shipped with its PowerBook G4 portable computer this year.
