what do you mean by " it dose not work "

151 is ancient
likely you will need to install Win XP on a VM and use that

161 a 2018 build

Re: Bugs with textures

if it has a ring then it might be a graphics issue , ie your 3d card/driver

or it might be a issue with your ssc file

but without more information it is near impossible to diagnose

Re: Using DE441 ephemerides

Apple is a BSD ( Berkley Software Distribution) type of operation system and as such is in the UNIX family

a " _" underscore is just fine

now Blank Spaces can cause problems sometimes

Re: Using DE441 ephemerides

Solarsystem.SPICE.ssc
dose not go in the data folder , it goes in "SpiceSolarSystem"

only the spice kernels go in " data"

you also need to make sure that the Apple version of Celestia is built with spice enabled

i do not use apple so i do not know if it is or not
