Macarius is first mentioned in a fragmentary charter he issued as royal notary in the reign of King Stephen II of Hungary. The charter is dated to the period between 1125 and 1128, and refers to him as the head or provost of the collegiate chapter at Titel. Macarius is first mentioned as bishop at the beginning of 1137. This year he participated at the assembly where Ladislaus, a younger son of King Béla II of Hungary was proclaimed Duke of Bosnia. In the list of the participants, Macarius is only preceded by the archbishop of Esztergom. His see at Pécs is revealed in a charter issued for the Dömös Chapter by King Béla II on September 3, 1138. Another charter, which donated villages to the monastery of Csatár, erected by Martin Gutkeled, ispán of Zala County, also refers to Macarius as bishop, but without mentioning his see. The charter is dated to the period between 1138 and 1141, the last years of Béla II. Macarius seems to have been transferred to the see of Esztergom in some years, because three charters issued between 1142 and 1146 refer to one "Archbishop Macarius". As Jesuit scholar István Katona considered at the turn of the 18th and 19th centuries, it is presumable that Macarius is identical with that certain Archbishop "Muchia", who appears without giving the specific archdiocese in a document in May 1142, when the privileges of Split were confirmed by the royal court in the name of the minor King Géza II of Hungary. However historian Tamás Körmendi emphasizes the paleographic difficulties between the two name forms, while the authenticity of the charter itself is also doubtful. Nándor Knauz, Imre Szentpétery, László Koszta, Attila Zsoldos and – after philological and canon law considerations – Tamás Körmendi accepted Katona's claim, while József Udvardy identified "Muchia" as a previously unknown Archbishop of Kalocsa. He is still referred to as archbishop by two charters in 1146. Macarius appeared as a witness both times on the occasion of the last testaments of lady Színes or Scines and hospes Fulco, who served different prelates for decades as a secular clergyman. Macarius' name also appears in an undated royal charter, when Géza II returned the privilege of the imposition of duty near Győr to the Pannonhalma Archabbey. According to the obituary of the Göttweig Abbey, Macarius died on 25 January, without mentioning the proper year. As Fulco's last testament took place after 16 February 1146, Macarius passed away sometimes from 25 January 1147 at the earliest to the same day in 1150 at the latest, as Kökényes already functioned as archbishop in that year.
