download photos icloud but not upload my photo library from my mac to the cloud.

Hello there, laq.

It sounds like you are trying to sync photos manually from your computer to your iPhone, without using iCloud Photo Library. The following Knowledge Base article offers up some great information in regards to that:

Keep your photos safely stored and up to date on all your devices

If you choose not to turn on iCloud Photo Library, you can sync your photos and videos manually in iTunes.

Sync your photos manually with iTunes

You can set up iTunes to sync photos to your iPhone, iPad, or iPod touch from the Photos app, or from a folder on your computer. Each time that you sync your iOS device with iTunes, the photos and videos on your iOS device will update to match the albums on your computer. If you have photos on your iPhone, iPad, or iPod touch that aren't on your computer, follow these steps to import them.

1. Make sure that you have the latest version of iTunes.
2. Open iTunes on your computer.
3. Use the included USB cable to connect your iPhone, iPad, or iPod touch to your computer.
4. Click on the device icon in iTunes.
5. Click Photos in the sidebar.
6. Click the box next to "Sync Photos." If instead you see "iCloud Photos is On," all your photos and videos are already on all of your devices that use iCloud Photo Library. You don't need to sync them through iTunes.
7. In the drop-down menu, choose the app or folder that you want to sync from.
   
8. Choose to sync all photos or selected albums.
9. Select "Include videos" to sync the videos from your app or folder too.
10. Click Apply.

You must import Slo-Mo and Time-Lapse videos through the Photos app or Image Capture in OS X Yosemite or later for their effect to be synced via iTunes. You can also sync Slo-Mo and Time-Lapse videos when you use iCloud Photo Library.
