Hover on iOS Safari - html

Question

This menu in the middle of this page is working well, but on a Mac tablet (IOS system) it is giving this bug hover menu on Mac IOS. I suspect the problem to come from the "hover" function. Here is the html code :
.accueil2 {
text-align: center;
width: 70%;
}
.hover {
background-color: #fff;
}
.wrap {
position: relative;
width: 60vmin;
height: 60vmin;
margin: 0 auto;
top: -10vmin;
-webkit-transform: scale(0.2) translatez(0px);
transform: scale(0.2) translatez(0px);
opacity: 0;
-webkit-transition: opacity .5s, -webkit-transform .5s;
transition: opacity .5s, -webkit-transform .5s;
transition: transform .5s, opacity .5s;
transition: transform .5s, opacity .5s, -webkit-transform .5s;
