If I delete Photos app from iCloud Drive will it be deleted from my Mac too?

Also, if might of significance to note that since all this,

and deleting some hundreds of photos on iCloud Photos + Mac Photo app

I can't get into the Apple > Sys Pref > iCloud --- clicking that icon and the spinning wheel happens

and I have to force quite Sys Pref to close the panel.

You ask, What exact, specific iCloud services are you using?

I am using iCloud Drive and iCloud: Photos, Contacts, Mail, Bookmarks + Favorites options only

and only with one MacBook Air 10.10.5 with a Photos 1.0.1 (215.65.0)

__________

iCloud Drive says that it will deleted whatever is deleted from "all iOS devices".

You say, "...so in general anything deleted form any connected data set will be deleted from all connected devices." Clarification please: is the MacBook Air an iOS device, or are iOS devices not the computer/Mac

but the phones, pads, etc?? This is simple but this is what I want to know.

I don't know how it happened but I "uploaded" the Mac Photo app to iCloud Drive,

have now deleted it and deleted all deletions: is the Photo app on my Mac going to be deleted?!

Please, again this is elementary, but this is what I want to know.

What I want to achieve is peace of mind that the Mac Photo app is not going to disappear.

I also would like to be able to go into the Apple>SysPref>iCloud without a spinning wheel

happening and my having to force quit SysPref to close the panel.

I think I have to 'playing around' with the iCloud Photos and iCloud Drive too much and

that that is why the spinning wheel is happening and hoping it will work itself out if I give

it the 40 days for complete completion of the hundreds of photos I deleted to register

properly -- they are gone from MacPhotos (deleted manually) and from iCloud Photos

(deleted manually) and in both cases deleted the deletions; so currently all appears

fine but don't want to be surprised in 40 days and find that the MacPhotos app has

been deleted from iCloud Drive deletion of the uploading of the app which I did today.

Want to achieve getting the spinning wheel to stop, or knowing it will with patience.

Want to achieve peace of mind that when the iCloud Drive says it will delete item

from all "iOS devices" this does not include the Mac Photos.

I am very grateful for you hanging in there with me, your obvious patience and

understanding.

All the best.

The icon at iCloud Drive said "Photos app" and when I clicked it showed material

being transferred with 'zip' in the label.

I check the Library.photos library in Finder and when I clicked it it opened

Mac Photos and everything was as it should be.

When I opened Mac Photos everything was as it should be too.

Am I okay or can there be a delay in iCloud Drive deleting Mac Photos.

Why did it says it would delete from all "iOS devices" and somethings

the Apple articles seem to be distinguishing these from "computer" -

So is it for sure under these circumstances that iCloud Drive will eventually

delete my Mac Photos!!!!!??
